CDNA cloning of a short isoform of human liver NADP (H) -dependent retinol dehydrogenase/reductase and analysis of its characteristics.
In this report we found a new short PCR product when we amplified a 635 bp of NRDR fragment by RT-PCR. With 3'-Race and 5'-Race,we obtained two full-length cDNA sequences from human liver tissue,one 1 261 bp NRDR cDNA,another 1 003 bp NRDR isoform (NRDRiso,GenBank accession number:AY071856). The NRDR gene comprises eight exons and seven introns. The NRDRiso cDNA is produced by alternative splicing of NRDR cDNA, with the removal of 4, 5, 6 exons composed of consecutive 258 bp. The open reading frames of the NRDRiso cDNA predict a single polypeptide of 174 amino acids with the calculated minimum molecular mass of 18.6 kDa.
