Product Overview
Clone 23B56 is a rabbit monoclonal antibody that recognizes breast cancer anti-estrogen resistance protein 1 (gene BCAR1) in human, mouse and rat samples and is validated for Western blot. The predicted molecular weight is 93.4 kDa, and the supplier reports an observed band at about 130 kDa.
BCAR1 (p130Cas) is a docking protein at focal adhesions that becomes tyrosine phosphorylated by FAK and SRC after integrin engagement. Its phosphorylated substrate domain recruits CRK and other adaptors that drive actin remodeling and cell migration. BCAR1 was identified through resistance to antiestrogens in breast cancer cells and is widely studied in adhesion signaling.

Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places breast cancer anti-estrogen resistance protein 1 in the cell junction, cytoplasm and cell projection. Tissue expression noted by UniProt (human): Expressed in B-cells (at protein level). The samples tested by the supplier (listed above) are a practical starting point for positive controls.
