FunctionDeoxycytidyl transferase involved in DNA repair. Transfers a dCMP residue from dCTP to the 3'-end of a DNA primer in a template-dependent reaction. May assist in the first step in the bypass of abasic lesions by the insertion of a nucleotide opposite the lesion. Required for normal induction of mutations by physical and chemical agents.
Sequence similaritiesBelongs to the DNA polymerase type-Y family. Contains 1 BRCT domain. Contains 1 umuC domain.
DomainThe C-terminal domain is necessary for protein interactions.
