When the cDNA for PCNA/cyclin was cloned and analyzed, it was found that the protein consisted of 261 amino acids with a calculated molecular weight of 28, 700 and the amino acid sequence was well conserved during evolution both in animal and plant kingdoms. The highly homologous nature of PCNA/cyclin suggests that the protein plays an essential role in DNA replication in eukaryotes., Acta Histochemica et Cytochemica, 22(1), pp.105-116; 1989}, pages = {105--116}, title = {Proliferating Cell Nuclear Antigen (Pcna/Cyclin): Review and Some New Findings (Histo- and Cytochemistry in Tissue Culture)}, volume = {22}, year = {1989} }
