third BRCT domain of Schizosaccharomyces pombe S-M checkpoint control protein Rad4 and similar proteins
Rad4, also termed P74, or protein cut5, is an essential component for DNA replication and the checkpoint control system which couples S and M phases. It may directly or indirectly interact with chromatin proteins to form the complex required for the initiation and/or progression of DNA synthesis. Rad4 contains four BRCT repeats. The family corresponds to the third repeat.
