 369-435 1.11e-41

SAM domain of LBP1 (UBP1) transcription factors; SAM (sterile alpha motif) domain of LBP1 (also known as UBP1) transcription factor is a putative protein-protein interaction domain. Proteins of this group have an N-terminal DNA-binding CP2 domain, a central predicted SAM domain and some also have a C-terminal dimerization domain. They are involved in transcriptional regulation from early development to terminal differentiation. In particular, they regulate alpha-globin in erythroid cells and P450scc (the cholesterol side-chain cleavage enzyme, cytochrome) in human placenta. Human LBP1 is known to be induced by HIV type I infection in lymphocytes; it represses HIV transcription by preventing the binding of TFIID to the virus promoter. Additionally, it has been suggested that UBP1 (LPB1) regulator might be a member of a blood pressure controlling network. LBP1 protein isoforms are able to form dimers, apparently via SAM domain since SAM deletion or mutation resulted in a loss of this ability.

Proteins of this group have an N-terminal DNA-binding CP2 domain, a central predicted SAM domain and some also have a C-terminal dimerization domain. CP2-like family of transcriptional factors includes three subgroups: LBP1, TFCP2, and LBP9. Members of this family are involved in transcriptional regulation from early development to terminal differentiation. They play a role in regulation of expression of P450scc (the cholesterol side-chain cleavage enzyme, cytochrome) in placenta, and alpha-globin in erythroid cells. They are required for proper maturation of the dust (epithelial component of tubular organs) of kidney and salivary gland. Human LBP1 is known to be induced by HIV type I infection in lymphocytes; it represses HIV transcription by preventing the binding of TFIID to the virus promoter. Additionally, it has been suggested that UBP1 (LBP1) regulator might be a member of a blood pressure controlling network.

Proteins of this group have an N-terminal DNA-binding CP2 domain, a central predicted SAM domain and a C-terminal dimerization domain. They are involved in transcriptional regulation from early development to terminal differentiation. In particular, they regulate expression of erythroid cell-specific alpha-globin, fibrinogen, and sex-determining gene SRY as well as lens alpha-crystallin. TFCP2 regulators can interact with NF-E4 proteins forming heteromeric stage selector protein complex (SSP). This complex is able to bind stage selector element (SSE) and regulate embryonic globin expression in fetal-erythroid cells.

 363-421 8.49e-05

SAM domain of EPS8-like subfamily; SAM (sterile alpha motif) domain of EPS8-like subfamily is a putative protein-protein interaction domain. This subfamily includes epidermal growth factor receptor kinase substrate 8 proteins (EPS8) and epidermal growth factor receptor kinase substrate 8-like (EPSL8) 1, 2, 3 proteins with the SAM domain located in the C-terminal effector region. This region is responsible for intracellular protein localization and is involved in small GTPases (such as Rac and Rab5) activation/inhibition. Proteins belonging to this group participate in coordination and integration of multiple signaling pathways; in particular, they play a role in the control of actin dynamics and in receptor endocytosis. They can form complexes with other proteins; for example, in the actin signaling network they interact with SOS1 and E3b1 (Abl1) proteins as well as with CRIB (via SH3 domains) during the actin filament formation, and in the receptor endocytosis their partner is RN-tre protein.

 374-422 1.92e-04

SAM (Sterile alpha motif ); SAM (Sterile Alpha Motif) domain is a module consisting of approximately 70 amino acids. This domain is found in the Fungi/Metazoa group and in a restricted number of bacteria. Proteins with SAM domains are represented by a wide variety of domain architectures and have different intracellular localization, including nucleus, cytoplasm and membranes. SAM domains have diverse functions. They can interact with proteins, RNAs and membrane lipids, contain site of phosphorylation and/or kinase docking site, and play a role in protein homo and hetero dimerization/oligomerization in processes ranging from signal transduction to regulation of transcription. Mutations in SAM domains have been linked to several diseases.
