Summary: Predicted to enable DNA-directed DNA polymerase activity. Involved in embryo development; error-prone translesion synthesis; and negative regulation of mitotic DNA damage checkpoint. Located in nucleus. Human ortholog(s) of this gene implicated in female breast cancer and xeroderma pigmentosum variant type. Orthologous to human POLH (DNA polymerase eta).

What's a GeneRIF?

SUMO-mediated regulation of both POLH-1 and POLK-1, and point towards a previously unrecognized role of the nuclear pore in regulating Translesion synthesis .
Title: A broad requirement for TLS polymerases η and κ, and interacting sumoylation and nuclear pore proteins, in lesion bypass during C. elegans embryogenesis.
These studies reveal that POLH-1 undergoes DNA-damage-induced proteolysis and that GEI-17 regulates the timing of this proteolysis.
Title: Regulated proteolysis of DNA polymerase eta during the DNA-damage response in C. elegans.
findings indicate that Poleta contributes significantly to damage tolerance in early embryogenesis but only modestly at later stages; may confer UV resistance perhaps by catalyzing translesion synthesis in early embryogenesis
Title: Deficiency of the Caenorhabditis elegans DNA polymerase eta homologue increases sensitivity to UV radiation during germ-line development.
