The nuclear localization sequences of the BRCA1 protein interact with the importin-alpha subunit of the nuclear transport signal receptor.

The BRCA1 gene product is a nuclear phosphoprotein that is aberrantly localized in the cytoplasm of most breast cancer cells. In an attempt to elucidate the potential mechanism for the nuclear transport of BRCA1 protein, three regions of highly charged, basic residues, 503KRKRRP508, 606PKKNRLRRKS615, and 651KKKKYN656, were identified as potential nuclear localization signals (NLSs). These three regions were subsequently mutated ... [more]

Throughput

  • Low Throughput

Additional Notes

  • amino acids 1-1142 of BRCA1 bait;503KRKRRP508 and 606PKKNRLRRKS615 regions, but not 651KKKKYN656, are critical for this interaction
