the coding sequence for a 260-amino-acid residue polypeptide was interrupted by a single short intron of 60 base pairs ( bp ) , and about 70 % of the deduced amino acid sequence of the drosophila pcna was identical to the rat and human pcna polypeptides , with conserved unique repeats of leucine in the c-terminal region .
