A, B, C	PF12738	twin BRCT domain (PTCB-BRCT)	twin BRCT domain	This is a BRCT domain that appears in duplicate in most member sequences. BRCT domains are peptide- and phosphopeptide-binding modules. BRCT domains are present in a number of proteins involved in DNA checkpoint controls and DNA repair [1,2].	Domain
