WebOct 28, 2011 · Germline mutations of the breast cancer 1 (BRCA1) tumor suppressor are a common cause of hereditary breast and ovarian cancer.The BRCA1 protein harbors an N-terminal RING motif characteristic of many ubiquitin E3 ligases and two BRCA C terminus (BRCT) motifs that form a phosphoprotein recognition domain (1–4).BRCA1 interacts … WebMar 1, 2010 · INTRODUCTION. BRCA1 is a large nuclear phospho-protein that regulates the repair of double-strand breaks (DSBs) in DNA. It contains an N-terminal RING domain that functions as an E3 ubiquitin ligase when bound to its partner protein BARD1 ().BRCA1 also contains a C-terminal BRCT repeat domain (), that functions as phospho-protein …
