GPRC5A
Protein-coding gene in the species Homo sapiens
From Wikipedia, the free encyclopedia
Retinoic acid-induced protein 3 is a protein that in humans is encoded by the GPRC5A gene.[5][6] This gene and its encoded mRNA was first identified as a phorbol ester-induced gene, and named Phorbol Ester Induced Gen 1 (PEIG-1);[7] two years later it was rediscovered as a retinoic acid-inducible gene, and named Retinoic Acid-Inducible Gene 1 (RAIG1).[5] Its encoded protein was later named Retinoic acid-induced protein 3.

Function
This gene encodes a member of the type 3 G protein-coupled receptor family, characterized by the signature 7-transmembrane domain motif. The encoded protein may be involved in interaction between retinoic acid and G protein signalling pathways. Retinoic acid plays a important role in development, cellular growth, and differentiation. This gene may play a role in embryonic development and epithelial cell differentiation.[6] Tryptamine and other indole related chemicals produced by gut microflora bind and activate the receptor.[8]
Post transcriptional regulation
Clinical significance
GPRC5A is dysregulated in many human cancers and in other diseases.[10]
