BRCA1 C Terminus (BRCT) domain is a family of evolutionarily related proteins. It is named after the C-terminal domain of BRCA1, a DNA-repair protein that serves as a marker of breast cancer susceptibility.

The BRCT domain is found predominantly in proteins involved in cell cycle checkpoint functions responsive to DNA damage,^[2] for example as found in the breast cancer DNA-repair protein BRCA1. The domain is an approximately 100 amino acid tandem repeat, which appears to act as a phospho-protein binding domain.^[3]
