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.

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. LIM domains function as adaptors or scaffolds to support the assembly of multimeric protein complexes.

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.

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 N-terminal of abLIM consists of four tandem repeats of LIM domains and the C-terminal of acting binding LIM protein is a villin headpiece domain, which has strong actin binding activity. The abLIM-1, which is expressed in retina, brain, and muscle tissue, has been indicated to function as a tumor suppressor. AbLIM-2 and -3, mainly expressed in muscle and neuronal tissue, bind to F-actin strongly. They may serve as a scaffold for signaling modules of the actin cytoskeleton and thereby modulate transcription.

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.

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. Isl-1 is one of the LHX proteins isolated originally by virtue of its ability to bind DNA sequences from the 5'-flanking region of the rat insulin gene in pancreatic insulin-producing cells. Mice deficient in Isl-1 fail to form the dorsal exocrine pancreas and islet cells fail to differentiate. On the other hand, Isl-1 takes part in the pituitary development by activating the gonadotropin-releasing hormone receptor gene together with LHX3 and steroidogenic factor 1. Mouse Is l2 is expressed in the retinal ganglion cells and the developing spinal cord where it plays a role in motor neuron development. Same as Isl1, Isl2 may also be able to bind to the insulin gene enhancer to promote gene activation. All LIM domains are 50-60 amino acids in size and share two characteristic zinc finger motifs.

ALP contains an N-terminal PDZ domain, a C-terminal LIM domain and an ALP-subfamily-specific 34-amino-acid motif termed ALP-like motif (AM), which contains a putative consensus protein kinase C (PKC) phosphorylation site and two alpha-helices. ALP proteins are found in heart and in skeletal muscle. ALP may act as a signaling molecule which is regulated by PKC-dependent signaling. ALP plays an essential role in the development of RV (right ventricle) chamber. 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.
