Gene Gene information from NCBI Gene database.
Entrez ID 51426
Gene name DNA polymerase kappa
Gene symbol POLK
Synonyms (NCBI Gene)
DINB1DINPPOLQ
Chromosome 5
Chromosome location 5q13.3
Summary This gene encodes a member of the DNA polymerase type-Y family of proteins. The encoded protein is a specialized DNA polymerase that catalyzes translesion DNA synthesis, which allows DNA replication in the presence of DNA lesions. Human cell lines lacking

Protein name DNA polymerase kappa (EC 2.7.7.7) (DINB protein) (DINP)
Protein function DNA polymerase specifically involved in DNA repair. Plays an important role in translesion synthesis, where the normal high-fidelity DNA polymerases cannot proceed and DNA synthesis stalls. Depending on the context, it inserts the correct base,
