Gene Information

human ... BRCA1(672)

General description

The gene BRCA1 is mapped to human chromosome 17q21 and codes for a protein with zinc finger motif and a set of acidic residues. BRCA1 is localized to the nucleus and cytoplasm.

Immunogen

BRCA1 protein fragment expressed in E. coli corresponding to amino acids 341-748.

Application

Suggested starting dilutions are as follows: WB: 1:500-1:3000, ICC/IF: 1:100-1:1000, IHC, IP, ChIP. Not yet tested in other applications. Optimal working dilutions should be determined experimentally by the end user.

Biochem/physiol Actions

BRCA1-6B4 recognizes full length BRCA1, a 220 kDa nuclear phosphoprotein, and does not recognize the exon 11 splice variant. Mutations in this tumor suppressor gene greatly increase the risk of breast cancer. In a high proportion of breast and ovarian cancer cell lines, BRCA1 aberrantly mislocates to the cytoplasm. Recent studies suggest a role for BRCA1 in DNA double strand break repair because of its association with Rad51. BRCA1 is predominantly expressed in proliferating and differentiating cells and contributes to cellular growth.

BRCA1 mutation carriers are predisposed to developing basal-like breast cancers with high metastasis and poor prognosis. Yet, how BRCA1 suppresses formation of basal-like breast cancers is still obscure. Deletion of p18(Ink4c) (p18), an inhibitor of CDK4 and CDK6, functionally inactivates
