Species cross-reactivity is determined by western blot.

Applications Key: W=Western Blotting, IP=Immunoprecipitation,

Specificity / Sensitivity

BCAR3 antibody recognizes endogenous levels of total BCAR3 protein.

Source / Purification

Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Pro526 of human BCAR3 protein. Antibodies are purified by protein A and peptide affinity chromatography.

Western Blotting

Western Blotting

Western blot analysis of extracts from various cell lines using BCAR3 Antibody.



Immunoprecipitation of BCAR3 protein from ACHN cell extracts. Lane 1 is 10% input, lane 2 is Normal Rabbit IgG #2729, and lane 3 is BCAR3 Antibody. Western blot analysis was performed using BCAR3 Antibody.


BCAR3 is a member of the novel SH2-containing protein (NSP) family (1). It was identified as a gene product involved in anti-estrogen resistance in the context of breast cancer (2). Like other members of this family, BCAR3 has been shown to interact with the family member, CAS. The C terminal Cdc25 homolgy domain of BCAR3 interacts tightly with the FAT domain of p130Cas (3) and promotes the association of p130cas with Src kinase (4) to activate related signaling pathways. Overexpression of BCAR3 leads to the activation of a wide range of downstream signaling proteins including PI3K, rac, PAK1, and cyclin D1 (5-7). The main role of BCAR3 is to promote cell motility and regulate cytoskeletal remodeling and adhesion through its effect on p130cas and Src kinase (8-10). BCAR3 also has been implicated in playing an inhibitory role on TGF-β/SMAD signaling, which is associated with favorable disease outcomes (11).
