Abstract:

The study was conducted to clone sheep YAP1 CDS and construct a eukaryotic expression plasmid and a mutant that could not be phosphorylated at Ser42. The CDS of sheep YAP1 was amplified by RT-PCR from healthy sheep longissimus dorsi muscle, and was cloned into pMD19-T simple vector by T/A Ligation to sequence the DNA fragment. After double digestion, YAP1 coding region was subcloned into pEGFP-C1 vector by T4 Ligase to construct a eukaryotic expression plasmid and then make the eukaryotic expression vector as the template to construct the phosphorylation site mutant. PCRrestriction endonucleases analysis and sequencing were used to conform both of the recombinant plasmids. The sheep full-length YAP1 cDNA sequence was 1 712 bp in length encoding 403 amino acids. It was confirmed that the sheep YAP1 CDS was correctly inserted into eukaryotic expression vector and serine had been mutated to alanine at 42ed amino acid by PCRrestriction digestion and sequencing. The results showed that the recombinant plasmid pEGFP-C1-YAP1 and pEGFP-C1-YAP1 S42A was constructed correctly, which paved the foundation for further studies on the YAP1 protein expression and its biological activities.
