Fanconi anemia group J protein is a protein that in humans is encoded by the BRCA1-interacting protein 1 (BRIP1) gene.[5][6][7]

Function

The protein encoded by this gene is a member of the RecQ DEAH helicase family and interacts with the BRCT repeats of breast cancer, type 1 (BRCA1). The bound complex is important in the normal double-strand break repair function of breast cancer, type 1 (BRCA1). This gene may be a target of germline cancer-inducing mutations.[7]

This protein also appears to be important in ovarian cancer where it seems to act as a tumor suppressor.[8] Mutations in BRIP1 are associated with a 10-15% risk of ovarian cancer.[9]

BRIP1 appears to have an important role in neuronal cells by suppressing oxidative stress, excitotoxicity induced DNA damage, and in protecting the integrity of mitochondria.[10] A deficiency of BRIP1 causes increased DNA damage, mitochondrial abnormalities and neuronal cell death.

DNA repair

BRIP1 protein is a DNA helicase that is employed in homologous recombinational repair, and in the response of the cell to DNA replication stress.[11] In part, BRIP1 carries out its function through interaction with other key DNA repair proteins, specifically MLH1, BRCA1 and BLM.[11] This group of proteins helps to ensuring genome stability, and in particular repairs DNA double-strand breaks during prophase 1 of meiosis.

Interactions

BRIP1 has been shown to interact with BRCA1.[12][13][14][15][16][17]
