breast cancer type 1 susceptibility protein is a protein that in humans is encoded by the brca1 / ˌ b r æ k ə ˈ w ʌ n / gene. orthologs are common in other vertebrate species, whereas invertebrate genomes may encode a more distantly related gene. brca1 is a human tumor suppressor gene also known as a caretaker gene and is responsible for repairing dna.. brca1 and brca2 are unrelated .
the dual repeat brct domain of the brca1 protein is an elongated structure approximately 70 å long and 30–35 å wide. the 85–95 amino acid domains in brct can be found as single modules or as multiple tandem repeats containing two domains.
