Polymerase eta is particularly important for allowing accurate translesion synthesis of DNA damage resulting from ultraviolet radiation or UV.

This polymerase is thought to be involved in hypermutation during immunoglobulin class switch recombination.

Mutations in this gene result in XPV, a variant type of xeroderma pigmentosum, characterized by sun sensitivity, elevated incidence of skin cancer, and at the cellular level, by delayed replication and hypermutability after UV-irradiation[9][10] POLH has been shown to interact with PCNA.
