LIM is a small protein-protein interaction domain, containing two zinc fingers; LIM domains are identified in a diverse group of proteins with wide variety of biological functions, including gene expression regulation, cell fate determination, cytoskeleton organization, tumor formation and development. LIM domains function as adaptors or scaffolds to support the assembly of multimeric protein complexes. They perform their functions through interactions with other protein partners. LIM domains are 50-60 amino acids in size and share two characteristic highly conserved zinc finger motifs. The two zinc fingers contain eight conserved residues, mostly cysteines and histidines, which coordinately bond to two zinc atoms. The consensus sequence of LIM domain has been defined as C-x(2)-C-x(16,23)-H-x(2)-[CH]-x(2)-C-x(2)-C-x(16,21)-C-x(2,3)-[CHD] (where X denotes any amino acid).

The third LIM domain of the paxillin like protein family; The third LIM domain of the paxillin like protein family: This family consists of paxillin, leupaxin, Hic-5 (ARA55), and other related proteins. There are four LIM domains in the C-terminal of the proteins and leucine-rich LD-motifs in the N-terminal region. Members of this family are adaptor proteins to recruit key components of signal-transduction machinery to specific sub-cellular locations. Paxillin is found at the interface between the plasma membrane and the actin cytoskeleton. Paxillin serves as a platform for the recruitment of numerous regulatory and structural proteins that together control the dynamic changes in cell adhesion, cytoskeletal reorganization and gene expression that are necessary for cell migration and survival. Leupaxin is a cytoskeleton adaptor protein, which is preferentially expressed in hematopoietic cells. It associates with focal adhesion kinases PYK2 and pp125FAK and identified to be a component of the osteoclast pososomal signaling complex. Hic-5 controls cell proliferation, migration and senescence by functioning as coactivator for steroid receptors such as androgen receptor, glucocorticoid receptor and progesterone receptor. LIM domains are 50-60 amino acids in size and share two characteristic zinc finger motifs. The two zinc fingers contain eight conserved residues, mostly cysteines and histidines, which coordinately bond to two zinc atoms. LIM domains function as adaptors or scaffolds to support the assembly of multimeric protein complexes.

The third LIM domain of Leupaxin; The third LIM domain of Leupaxin: Leupaxin is a cytoskeleton adaptor protein, which is preferentially expressed in hematopoietic cells. Leupaxin belongs to the paxillin focal adhesion protein family. Same as other members of the family, it has four leucine-rich LD-motifs in the N-terminus and four LIM domains in the C-terminus. It may function in cell type-specific signaling by associating with interaction partners PYK2, FAK, PEP and p95PKL. When expressed in human leukocytic cells, leupaxin significantly suppressed integrin-mediated cell adhesion to fibronectin and the tyrosine phosphorylation of paxillin. These findings indicate that leupaxin may negatively regulate the functions of paxillin during integrin signaling. LIM domains are 50-60 amino acids in size and share two characteristic zinc finger motifs. The two zinc fingers contain eight conserved residues, mostly cysteines and histidines, which coordinately bond to two zinc atoms.

The first LIM domain of paxillin; The first LIM domain of paxillin: Paxillin is an adaptor protein, which recruits key components of the signal-transduction machinery to specific sub-cellular locations to respond to environmental changes rapidly. The C-terminal region of paxillin contains four LIM domains which target paxillin to focal adhesions, presumably through a direct association with the cytoplasmic tail of beta-integrin. The N-terminal of paxillin is leucine-rich LD-motifs. Paxillin is found at the interface between the plasma membrane and the actin cytoskeleton. The binding partners of paxillin are diverse and include protein tyrosine kinases, such as Src and FAK, structural proteins, such as vinculin and actopaxin, and regulators of actin organization. Paxillin recruits these proteins to their function sites to control the dynamic changes in cell adhesion, cytoskeletal reorganization and gene expression. LIM domains are 50-60 amino acids in size and share two characteristic zinc finger motifs. The two zinc fingers contain eight cons erved residues, mostly cysteines and histidines, which coordinately bond to two zinc atoms. LIM domains function as adaptors or scaffolds to support the assembly of multimeric protein complexes.

The second LIM domain of Enigma-like family; The second LIM domain of Enigma-like family: The Enigma LIM domain family is comprised of three members: Enigma, ENH, and Cypher (mouse)/ZASP (human). These subfamily members contain a single PDZ domain at the N-terminus and three LIM domains at the C-terminus. Enigma was initially characterized in humans and is expressed in multiple tissues, such as skeletal muscle, heart, bone and brain. The third LIM domain specifically interacts with the insulin receptor and the second LIM domain interacts with the receptor tyrosine kinase Ret and the adaptor protein APS. Thus Enigma is implicated in signal transduction processes, such as mitogenic activity, insulin related actin organization, and glucose metabolism. The second member, ENH protein, was first identified in rat brain. It has been shown that ENH interacts with protein kinase D1 (PKD1) via its LIM domains and forms a complex with PKD1 and the alpha1C subunit of cardiac L-type voltage-gated calcium channel in rat neonatal cardiomyocytes. The N-terminal PDZ domain interacts with alpha-actinin at the Z-line. ZASP/Cypher is required for maintenance of Z-line structure during muscle contraction, but not required for Z-line assembly. In heart, Cypher/ZASP plays a structural role through its interaction with cytoskeletal Z-line proteins. In addition, there is increasing evidence that Cypher/ZASP also performs signaling functions. Studies reveal that Cypher/ZASP interacts with and directs PKC to the Z-line, where PKC phosphorylates downstream signaling targets.

Four of the six LIM domains are highly homologous to the four and half LIM domain protein family and two of them show sequence similarity to the LIM domains of the testin family. Thus, LIMPETin may be the recombinant product of genes coding testin and FHL proteins. In Schistosoma mansoni, where LIMPETin was first identified, LIMPETin is down regulated in sexually mature adult Schistosoma females compared to sexually immature adult females and adult male. Its differential expression indicates that it is a transcription regulator. LIM domains are 50-60 amino acids in size and share two characteristic zinc finger motifs.

The first LIM domain of Lhx3a; The first LIM domain of Lhx3a: Lhx3a is a member of LHX protein family, which features two tandem N-terminal LIM domains and a C-terminal DNA binding homeodomain. Members of LHX family are found in the nucleus and act as transcription factors or cofactors. LHX proteins are critical for the development of specialized cells in multiple tissue types, including the nervous system, skeletal muscle, the heart, the kidneys, and endocrine organs, such as the pituitary gland and the pancreas. Lhx3a is one of the two isoforms of Lhx3. The Lhx3 gene is expressed in the ventral spinal cord, the pons, the medulla oblongata, and the pineal gland of the developing nervous system during mouse embryogenesis, and transcripts are found in the emergent pituitary gland. Lhx3 functions in concert with other transcription factors to specify interneuron and motor neuron fates during development. Lhx3 proteins have been demonstrated to directly bind to the promoters of several pituitary hormone gene promoters. The Lhx3 gene encodes two isoforms, LHX3a and LHX3b that differ in their amino-terminal sequences, where Lhx3a has longer N-terminal. They show differential activation of pituitary hormone genes and distinct DNA binding properties. In human, Lhx3a trans-activated the alpha-glycoprotein subunit promoter and genes containing a high-affinity Lhx3 binding site more effectively than the hLhx3b isoform. In addition, hLhx3a induce transcription of the TSHbeta-subunit gene by acting on pituitary POU domain factor, Pit-1, while hLhx3b does not. As in other LIM domains, this domain family is 50-60 amino acids in size and shares two characteristic zinc finger motifs. The two zinc fingers contain eight conserved residues, mostly cysteines and histidines, which coordinately bond to two zinc atoms. LIM domains function as adaptors or scaffolds to support the assembly of multimeric protein.

The second LIM domain of Four and a half LIM domains protein (FHL); The second LIM domain of Four and a half LIM domains protein (FHL): LIM-only protein family consists of five members, designated FHL1, FHL2, FHL3, FHL5 and LIMPETin. The first four members are composed of four complete LIM domains arranged in tandem and an N-terminal single zinc finger domain with a consensus sequence equivalent to the C-terminal half of a LIM domain. LIMPETin is an exception, containing six LIM domains. FHL1, 2 and 3 are predominantly expressed in muscle tissues, and FHL5 is highly expressed in male germ cells. FHL proteins exert their roles as transcription co-activators or co-repressors through a wide array of interaction partners. For example, FHL1 binds to Myosin-binding protein C, regulating myosin filament formation and sarcomere assembly. FHL2 has shown to interact with more than 50 different proteins, including receptors, structural proteins, transcription factors and cofactors, signal transducers, splicing factors, DNA replication and repair enzymes, and metabolic enzymes. FHL3 int eracts with many transcription factors, such as CREB, BKLF/KLF3, CtBP2, MyoD, and MZF_1. FHL5 is a tissue-specific coactivator of CREB/CREM family transcription factors. LIM domains are 50-60 amino acids in size and share two characteristic zinc finger motifs.

The second LIM domain of Leupaxin; The second LIM domain of Leupaxin: Leupaxin is a cytoskeleton adaptor protein, which is preferentially expressed in hematopoietic cells. Leupaxin belongs to the paxillin focal adhesion protein family. Same as other members of the family, it has four leucine-rich LD-motifs in the N-terminus and four LIM domains in the C-terminus. It may function in cell type-specific signaling by associating with interaction partners PYK2, FAK, PEP and p95PKL. When expressed in human leukocytic cells, leupaxin significantly suppressed integrin-mediated cell adhesion to fibronectin and the tyrosine phosphorylation of paxillin. These findings indicate that leupaxin may negatively regulate the functions of paxillin during integrin signaling. LIM domains are 50-60 amino acids in size and share two characteristic zinc finger motifs. The two zinc fingers contain eight conserved residues, mostly cysteines and histidines, which coordinately bond to two zinc atoms.
