Abstract
The cDNA and fourth intron sequences of porcine NPM1 gene were cloned,and verified by bioinformatics method.The cDNA fragment was 1 195 bp with an entire open reading frame(ORF),encoding 294 amino acids.The intron fragment was 300 bp and splice junctions follow 'GT/AG' rule.The analysis of sequence revealed that the porcine NPM1 gene was highly homologous with that of other species such as human(95%),mouse(91%) and rattus norvegicus(91%) in amino acid.The protein encoded by porcine NPM1 gene had a conserved domain 'Nucleoplasmin'.This gene was assigned to SSC16q21 region and closely linked to SW977 with the LOD of 9.16 by SCHP and IMpRH mapping,respectively.
