Figure 2. BRCA1 and BRCA2 structure and functions.

Schematic representations of BRCA1 (A) and BRCA2 (B) structural motifs, interacting proteins, and corresponding kinase phosphorylation sites. Both BRCA1 and BRCA2 regulate DNA double-strand breaks repair; however, BRCA1 is also involved in mediating ubiquitination and transcriptional control.
