Nucleotide sequence of a human genomic DNA fragment containing the PCNA pseudogene and its localization on chromosome 4

Abstract

A one kb human genomic DNA fragment, containing a processed pseudogene of a proliferating cell nuclear antigen (PCNA/DNA polymerase delta auxiliary protein), was isolated and sequenced. The PCNA pseudogene consisted of the 3' half of exon 4 and the 5' half of exon 5 of the PCNA gene, and shared 84% nucleotide homology with the human PCNA cDNA. The PCNA pseudogene was localized on human chromosome 4, based on data obtained from a panel of human-mouse hybrid cell lines.
