The gene product may play a role in degradation and maturation of tachykinins, neuropeptides, and peptide hormones. Alternative splicing results in multiple transcript variants.[provided by RefSeq, Nov 2009] Expression Ubiquitous expression in small intestine (RPKM 32.0), duodenum (RPKM 25.3) and 25 other tissues See more Orthologs mouse all
