AB In a previous study, the mRNA level of a pancreatitis-associated protein (PAP)-like protein was found to be elevated in the ileal Peyer's patch of lambs during the early phase of scrapie infection. Here, we report the isolation of the ovine PAP-like protein cDNA which encodes a putative 178 amino acid protein with a signal peptide and a C-lectin binding domain. Comparisons of REG/PAP proteins between various species showed that the deduced amino acid sequences were conserved. The overall amino acid identity between the ovine PAP-like protein and bovine, human and rat REG/PAP proteins varied from 23% to 85%. In Northern blot analysis the expression of the ovine PAP-like protein mRNA was restricted to the ileal and jejunal Peyer's patches. The cellular expression of the PAP-like protein mRNA in the ovine intestine was further characterized by in situ hybridization. PAP-like protein mRNA was detected in cells of the epithelial lining in most crypts and in some intestinal villi in the ileum and jejunum while in the colon and rectum, the PAP-like protein mRNA expression was only detected in the deep portion of a few crypts. The data provided will offer the possibility to search for a link between this PAP-like protein and early events in the development of scrapie.
