RAD17 is a linear chain of amino acid residues that resembles DNA replication factor C (RFC) and can form a complex with RFCs, it attaches itself to chromatin before DNA damage and is phosphorylated by ATR after the damage.
This protein shares strong similarity with DNA replication factor C (RFC), and can form a complex with RFCs. This protein binds to chromatin prior to DNA damage and is phosphorylated by ATR after the damage. Cell cycle checkpoint protein RAD17 is a protein that in humans is encoded by the RAD17 gene. This protein recruits the RAD1-RAD9-HUS1 checkpoint protein complex onto chromatin after DNA damage, which may be required for its phosphorylation.
