Human Gene BCAR1 (uc002fdv.3) Description and Page Index
  Description: Homo sapiens breast cancer anti-estrogen resistance 1 (BCAR1), transcript variant 6, mRNA.
RefSeq Summary (NM_014567): The protein encoded by this gene is a member of the Crk-associated substrate (CAS) family of scaffold proteins, characterized by the presence of multiple protein-protein interaction domains and many serine and tyrosine phosphorylation sites. The encoded protein contains a Src-homology 3 (SH3) domain, a proline-rich domain, a substrate domain which contains 15 repeat of the YxxP consensus phosphorylation motif for Src family kinases, a serine-rich domain, and a bipartite Src-binding domain, which can bind both SH2 and SH3 domains. This adaptor protein functions in multiple cellular pathways, including in cell motility, apoptosis and cell cycle control. Dysregulation of this gene can have a wide range of effects, affecting different pathways, including cardiac development, vascular smooth muscle cells, liver and kidney function, endothelial migration, and cancer.

DESCRIPTION: RecName: Full=Breast cancer anti-estrogen resistance protein 1; AltName: Full=CRK-associated substrate; AltName: Full=Cas scaffolding protein family member 1; AltName: Full=p130cas;
FUNCTION: Docking protein which plays a central coordinating role for tyrosine kinase-based signaling related to cell adhesion. Implicated in induction of cell migration. Overexpression confers antiestrogen resistance on breast cancer cells.
SUBUNIT: Forms complexes in vivo with PTK2/FAK1, adapter protein CRKL and LYN kinase. Can heterodimerize with NEDD9. Interacts with BCAR3, NPHP1 and SH2D3C (By similarity). Interacts with activated CSPG4. Interacts with BMX, INPPL1/SHIP2 and PEAK1. Part of a collagen-stimulated complex involved in cell migration made of CDC42, CRK, TNK2 and BCAR1/p130cas. Interacts with TNK2 via SH3 domains. Interacts with PTK2B/PYK2.
INTERACTION: P46108:CRK; NbExp=2; IntAct=EBI-702093, EBI-886; O15357:INPPL1; NbExp=2; IntAct=EBI-702093, EBI-1384248; Q9C0H9:SRCIN1; NbExp=3; IntAct=EBI-702093, EBI-1393949; Q9QWI6:Srcin1 (xeno); NbExp=3; IntAct=EBI-702093, EBI-775592; Q04205:TNS (xeno); NbExp=2; IntAct=EBI-702093, EBI-2607590; Q68CZ2:TNS3; NbExp=8; IntAct=EBI-702093, EBI-1220488;
SUBCELLULAR LOCATION: Cell junction, focal adhesion. Cytoplasm. Note=Unphosphorylated form localizes in the cytoplasm and can move to the membrane upon tyrosine phosphorylation (By similarity).
TISSUE SPECIFICITY: Widely expressed with an abundant expression in the testis. Low level of expression seen in the liver, thymus, and peripheral blood leukocytes. The protein has been detected in a B-cell line.
DOMAIN: Contains a central domain (substrate domain) containing multiple potential SH2-binding sites and a C-terminal domain containing a divergent helix-loop-helix (HLH) motif. The SH2- binding sites putatively bind CRK, NCK and ABL1 SH2 domains. The HLH motif is absolutely required for the induction of pseudohyphal growth in yeast and mediates heterodimerization with NEDD9 (By similarity).
DOMAIN: A serine-rich region promotes activation of the serum response element (SRE).
DOMAIN: The SH3 domain is necessary for the localization of the protein to focal adhesions and interacts with one proline-rich region of PTK2/FAK11.
PTM: PTK2/FAK1 activation mediates phosphorylation at the YDYVHL motif; phosphorylation is most likely catalyzed by SRC family members. SRC-family kinases are recruited to the phosphorylated sites and can phosphorylate other tyrosine residues. Tyrosine phosphorylation is triggered by integrin-mediated adhesion of cells to the extracellular matrix.
SIMILARITY: Belongs to the CAS family.
SIMILARITY: Contains 1 SH3 domain.

-  Orthologous Genes in Other Species
  Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
