Breast Cancer
Findings from J. Xu and co-authors broaden understanding of breast cancer
June 4th, 2009
"BRCA1 dysfunction is associated with hormone-responsive cancers. We have identified a consensus SUMO modification site in the amino-terminal region of BRCA1/1a/1b proteins and the mutation in this potential SUMO acceptor site (K 109 to R) impaired their ability to bind and repress ligand-dependent ER alpha transcriptional activity in breast cancer cells," scientists in the United States report. "Furthermore, we have found SUMO E2-conjugating enzyme Ubc9 to bind BRCA1 proteins. We have mapped BRCA1 [within amino acids (aa) 1-182] as the minimum domain that is sufficient for in vitro binding to Ubc9 as well as for regulating ER alpha activity. BRCA1 Mutant #1 (K 109 to...
