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.
分离并测序了一段1千碱基对的人类基因组DNA片段,该片段包含一个增殖细胞核抗原(PCNA/DNA聚合酶δ辅助蛋白)的加工假基因。PCNA假基因由PCNA基因第4外显子的3' 半段和第5外显子的5' 半段组成,与人PCNA cDNA具有84%的核苷酸同源性。根据一组人-鼠杂交细胞系获得的数据,PCNA假基因定位于人类4号染色体上。
