Introduction of GPRC5B
G-protein coupled receptor family C group 5 member B (GPRC5B) is a protein encoded by the GPRC5B gene. This protein is one of the defined CPRC5 receptors (the others are GPRC5A, GPRC5C, GPRC5D), which are classified as family C G protein-coupled receptors (GPCRs). GPRC5 receptors share approximately 30-40% sequence homology to each other and 25% homology to the other family C members. Members of this superfamily are characterized by a signature 7-transmembrane domain motif. Analysis of the protein sequence reveals that CPRC5B contains short extracellular amino-terminal domains (ATDs). Moreover, this receptor undergoes alternative splicing and produces multiple transcript variants.

Functions of GPRC5B Membrane Protein
GPRC5B is broadly expressed in tissues of nematodes, flies, fish, birds, mice, and humans. Studies find that this protein potentially mediates the cellular effects of retinoic acid on G protein signaling. Moreover, it has been shown human GPRC5B mRNA is robustly expressed in the central nervous system (e.g., the cerebellum and other brain regions) and in the adipose tissues. Studies have suggested that this receptor is associated with several human diseases, such as obesity, attention-deficit/hyperactivity disorder, and major depression.
Application of GPRC5B Membrane Protein in Literature
This article investigated both the mRNA and protein expression profiles of GPRC5B in the rat brain and spinal cord.
This article used GPRC5B-deficient mice to study the functions of this protein in the central nervous system and GPRC5B-deficient mice showed altered spontaneous activity pattern and decreased response to a new environment. Expression of this protein was regulated during the brain development.
This article studied GPRC5B expression in mouse and human pancreatic islets and the results suggested that the pharmacological targeting of GPRC5B might provide a novel means therapy for the treatment and prevention of type-2 diabetes.
This article found that GPRC5B was elevated in urinary exosomes from patients with acute kidney injury. Exosomal transfer of GPRC5B stimulated tubule growth via ERK1/2 activation and blockade of the apical release of this receptor via exomes decreased tubule growth.
This article studied the function of GPRC5B in Gprc5b-/- mice and the results suggested that GPRC5B played not only an important role in the development of distal axons of Purkinje cells and formation of synapses with deep cerebellar nuclei neurons but also in the synaptic plasticity that underlies long-term motor learning.
