Gene Gene information from NCBI Gene database.
Entrez ID 5111
Gene name Proliferating cell nuclear antigen
Gene symbol PCNA
Synonyms (NCBI Gene)
ATLD2
Chromosome 20
Chromosome location 20p12.3
Summary The protein encoded by this gene is found in the nucleus and is a cofactor of DNA polymerase delta. The encoded protein acts as a homotrimer and helps increase the processivity of leading strand synthesis during DNA replication. In response to DNA damage,
