G protein-coupled receptor 112 is a protein encoded by the ADGRG4gene.[5][6] GPR112 is a member of the adhesion GPCR family.[7][8]
Adhesion GPCRs are characterized by an extended extracellular region often possessing N-terminal protein modules that is linked to a TM7 region via a domain known as the GPCR-Autoproteolysis INducing (GAIN) domain.[9]
GPR112 is expressed in human enterochromaffin cells[10] and in the mouse intestine.[11] The N-terminal fragment (NTF) of GPR112 contains pentraxin (PTX)-like modules.[11] GPR112 gene expression has been identified as a marker for neuroendocrine carcinoma cells.[10]
