Family relationships


This entry includes animal BRCA1 (BREAST CANCER SUSCEPTIBILITY 1) proteins and their homologues from plants [PMID: 22629260].

The aimal BRCA1 protein is a E3 ubiquitin-protein ligase that specifically mediates the formation of 'Lys-6'-linked polyubiquitin chains and plays a central role in DNA repair by facilitating cellular responses to DNA damage [PMID: 10500182, PMID: 10724175]. It contains an N-terminal zinc-finger domain. It also contains a BRCT C-terminal domain, an approximately 100 amino acid tandem repeat, which appears to act as a phospho-protein binding domain [PMID: 14576433].

Arabidopsis BRCA1-related proteins includes AtBRCA1(AT4G21070, Q8RXD4) and AtBARD1 (AT1G04020, F4I443). Both are involved in DNA repair in plants [PMID: 16957774, PMID: 25527727]. AtBRCA1 can be induced by gamma-rays [PMID: 12582233]. AtBARD1, also known as Row1, functions mainly as a REPRESSOR OF WUSCHEL1, which is a transcription repressor required to regulate the maintenance of stem cell populations in shoot meristems [PMID: 19704708, PMID: 25631790].
