Cloning of a cDNA encoding rat intestinal 15 kDa protein and its tissue distribution

Biochem Biophys Res Commun. 1993 Jan 15;190(1):175-80. doi: 10.1006/bbrc.1993.1027.

Abstract

A cDNA encoding rat intestinal 15 kDa protein was isolated and sequenced from a rat ileum-specific cDNA library. This cDNA was found to contain an open reading frame of 384 nucleotides as well as 5' (27 nucleotides) and 3' (46 nucleotides) non-coding regions. The deduced sequence of 127 amino acids was identical to that of rat I-15P which was purified from rat intestinal epithelium. The nucleotide sequence of the open reading frame exhibited 79% identity to that of the porcine gastrotropin. Northern blot analysis indicated that the same size of transcript as that of the ileum was detected in the ovary, suggesting that I-15P or a homologous protein might be involved in the metabolism of steroids in steroid hormone-producing tissues.
