Function May act as an adapter protein and couple activated growth factor receptors to a signaling pathway that regulates the proliferation in breast cancer cells. When overexpressed, it confers anti-estrogen resistance in breast cancer cell lines. May also be regulated by cellular adhesion to extracellular matrix proteins.

BCAR3 Antibody: Breast cancer anti-estrogen resistance 3 (BCAR3) was identified in the search for genes involved in the development of estrogen resistance. It contains a putative src homology 2 (SH2) domain and is partly homologous to the cell division cycle protein CDC48. BCAR3 is a binding partner with Cas, an adapter molecule that plays a role in cell proliferation, survival, cell adhesion, and mobility. BCAR3 functions synergistically with Cas to enhance Src activation and promote cell migration, and has been suggested to regulate Cas/Src association, Src kinase activity, and breast cancer adhesion signaling.
