Facts about Breast cancer type 1 susceptibility protein.
The BRCA1-BARD1 heterodimer coordinates a wide range of cellular pathways such as DNA damage repair, ubiquitination and transcriptional regulation to maintain genomic stability. Required for normal cell cycle progression from G2 into mitosis.

Isoform 1 and isoform 3 are widely expressed. Isoform 3 is reduced or absent in several breast and ovarian cancer cell lines.
Nucleus. Chromosome. Cytoplasm. Localizes at sites of DNA damage at double-strand breaks (DSBs); recruitment to DNA damage sites is mediated by ABRAXAS1 and the BRCA1-A complex (PubMed:26778126). Translocated to the cytoplasm during UV-induced apoptosis (PubMed:20160719).; [Isoform 3]: Cytoplasm.; [Isoform 5]: Cytoplasm.
