MPH1/YIR002C Summary Help

Standard Name MPH1 1
Systematic Name YIR002C
Feature Type ORF, Verified
Description 3'-5' DNA helicase involved in error-free bypass of DNA lesions; binds to flap DNA in an error-free bypass pathway and stimulates the activity of Rad27p and Dna2p; also involved in interstrand cross-link repair mutations confer a mutator phenotype; similarity to FANCM, a human Fanconi anemia complementation group protein that along with the MHF complex is involved in stabilizing and remodeling blocked replication forks; member of the SF2 DExD/H superfamily of helicases (2, 3, 4, 5, 6, 7, 8)
Name Description Mutator PHenotype 1
