Comments
BRCA1 plays a role in transcriptional regulation and the cellular response to DNA damage. Inherited breast and ovarian cancers are linked to mutations in Brca1 gene. BRCA1 is capable of nucleo-cytoplasmic shuttling. BRCA1 exits the nucleus via CRM1-dependent pathway. AA 81-99 is sufficient to promote the export of fusion proteins.

User Input
Accurate identification of NESs is difficult because many sequences in the genome match the NES consensus. Therefore, some published NESs may be mistakenly identified. Please help us improve the accuracy of NESdb by providing either a positive or negative flag for the NES in this entry. Supporting comments are required to process the flag.
