Rabbit Galig Discovery and its Prokaryotic Recombinant Protein Expression

2018 International Journal of Research Studies in Biosciences  
In the process of cloning and analyzing rabbit (Oryctolagus cuniculus) galectin-3 (gal-3) cDNA, authors found that its open reading frame (ORF) is 729 bp encoding Gal-3 consisting of 242 amino acid residues, which is consistent with previous report. Meanwhile, two galig ORFs embedded in gal-3 were found, whose encoding polypeptides are completely different from that of Gal-3 but show 58% and 57% homology with human Cytogaligin and Mitogaligin, respectively. So far, the function of apoptosis

In consideration of the importance of further investigation on Cytogaligin and Mitogaligin, and the lack of direct detection of their apoptotic activity with protein samples, prokaryotic expression constructs of rabbit pET-28b-cytogaligin and pET-28b-mitogaligin as well as pET-28b-gal-3 were made in current investigation, however only recombinant Gal-3 and Cytogaligin of rabbit were well expressed.
