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.

Interactions[]

BRIP1 has been shown to interact with BRCA1.^{[11][12][13][14][15][16]}
