Uses
Detect BRCA1 with Anti-BRCA1 Antibody (Rabbit Polyclonal Antibody), that has been shown to work in IHC, IP & WB. This BRCA1 antibody has been tested in human samples.
General Description
Two major susceptibility genes for breast cancer, BRCA1 and BRCA2, have been identified. Both genes are considered to be tumor-suppressor genes. Mutations within BRCA1 and BRCA2 are responsible for most familial breast cancer cases. Functional analyses of the BRCA1 and BRCA2 gene products have established their dual participation in transcription regulation and DNA damage repair. BRCA1 affects cell cycle regulation and loss of BRCA1 function due to decreased expression leads to cell cycle arrest, through p53 and p21 genes. In vivo, BRCA1 and BRCA2 are expressed at maximal levels in rapidly proliferating cells. This feature is consistent with in vitro observations that BRCA1 and BRCA2 are expressed in a cell cycle-dependent manner. During mammary gland development, the expression of BRCA1 and BRCA2 is induced in rapidly proliferating cellular compartments.
