NCIt definition : Human BAP1 wild-type allele is located in the vicinity of 9q22.31 and is approximately
148 kb in length. This allele, which encodes ubiquitin carboxyl-terminal hydrolase
BAP1 protein, plays a role in tumor suppression. Homozygous BAP1 intragenic rearrangements
and allelic deletions occur in lung carcinoma.;
NCIt note : Murine BAP1 and BRCA1 are co-expressed during breast development and remodeling. BAP1
interacts with the BRCA1 RING finger, prevented by RING finger germline mutations.
BAP1 may be a tumor suppressor in the BRCA1 growth control pathway and enhances BRCA1
inhibition of breast cancer cell growth.;
