Abstract: In the present study,the RPLP1 gene was cloned by RT-PCR assay and was subsequently bioinformatically analyzed with bioinformatics analysis software,and the tissue expression profile of this gene was determined by semi-quantitative RT-PCR method.The results showed that cattle RPLP1 gene was composed of 502 nucleotides,including a single open reading frame of345 bp which encoded 114 amino acids;topology prediction analysis showed that there were three casein kinase Ⅱphosphorylation sites,two N-myristoylation sites and one Ribosomal-P1 conserved domain in RPLP1 protein;semi-quantitative RT-PCR assay showed that RPLP1 gene was widely expressed,and high expression was observed in skeletal,liver and cardiac muscle.
