GPR15L   

GtoPdb Ligand ID: 10567

Synonyms: antimicrobial peptide-57 | colon-derived SUSD2 binding factor
Comment: This peptide is a product of the human C10orf99 gene. It is proposed as an agonistic ligand of the orphan GPCR, GPR15, and has been referred to as GPR15L [1]. Structurally, GPR15L is predicted to contain two intramolecular disulphide bonds, which implies a similarity to CC family cytokines.
