abstractText | Mouse cDNA for the heart-type (H) isoform of AMP deaminase (EC 3.5.4.6., AMPD) has been isolated and characterized. The cDNA for the Ampd gene expressed in heart is predicted to encode a peptide of 766 amino acids with a molecular mass of 88 kDa. The coding region of this cDNA was quite homologous to the human AMPD3 gene which encodes the erythrocyte-type (E) isoform of AMPD, although the H-isoform of rodent AMPD was reported to be immunologically distinct from the E-isoform of human AMPD. The non-coding region of the isolated cDNA is not homologous to human AMPD3, while rodent Ampd1 has similarity to human AMPD1 in the non-coding region as well as in the coding region. The transcripts for the cloned cDNA were expressed in heart, slow-twitch skeletal muscle and non-muscle tissues. Prokaryotic expression showed that this cDNA encodes a catalytically active enzyme which reacts to the specific antibody raised to the H-isoform of AMPD. |
