What's a GeneRIF?

gene transcripts for CPA1 in mesentery and other extrapancreatic tissues indicate that CPA1 might play a role in the renin-angiotensin system in addition to it'sfunction as digestive enzyme
Title: Carboxypeptidases A1 and A2 from the perfusate of rat mesenteric arterial bed differentially process angiotensin peptides.
Data show that latexin protein expression was reduced after SNI, and the decrease of latexin was associated with an increase of the activity of carboxypeptidase A.
Title: Nerve injury evoked loss of latexin expression in spinal cord neurons contributes to the development of neuropathic pain.
carboxypeptidase A, dipeptidase and Na+/K+ ATPase levels in the rat intestine change when exposed to different doses of cadmium

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
