Generic protein structure example

Probable G-protein coupled receptor 25 is a protein that in humans is encoded by the GPR25 gene.[1][2]

Structure

It is a member of the G protein-coupled receptor (GPCR) family and it's well conserved in vertebrate evolution containing a canonical DRYLAVV motif in the third transmembrane sequence. It has a conserved negatively charged N-terminal extracellular peptide comprising a DY candidate sulfation site that is characteristic of many leukocyte chemoattractant receptors for positively charged polypeptides of the chemokine family.[3]

Tissue distribution

GPR25 expression is largely restricted to lymphocytes and natural killer (NK) cells.[3]

Function

It has been identified as the receptor for the chemokine-like protein CXCL17.[3]
