Characterization of canine caspase-3

The canine caspase-3 gene was cloned and sequenced. The canine caspase-3 cDNA clone was 1473 base pairs in length and encoded 277 amino acids. The predicted amino acid sequence showed 88.4%, 88.0%, 85.9%, 65.9% and 60.6% homology with that of human, pig, mouse, chicken and zebra fish caspase-3, respectively. The caspase-3 mRNA was confirmed to express in skin, lymph node, bone marrow, small intestine and lung from a healthy dog by RT-PCR analysis.
