BRIP1, also named as BACH1 and FANCJ, belongs to the DEAD box helicase family and DEAH subfamily. It is a DNA-dependent ATPase and 5' to 3' DNA helicase required for the maintenance of chromosomal stability. It is involved in the repair of DNA double-strand breaks by homologous recombination in a manner that depends on its association with BRCA1. Defects in BRIP1 are a cause of susceptibility to breast cancer (BC). Defects in BRIP1 are the cause of Fanconi anemia complementation group J (FANCJ). The antibody is specific to BRIP1.
