GPR98

Template:PBB G protein-coupled receptor 98, also known as GPR98 or VLGR1, is a protein that in humans is encoded by the GPR98 gene. Several alternatively spliced transcripts have been described.

Function

This gene encodes a member of the adhesion-GPCR family of receptors. The protein binds calcium and is expressed in the central nervous system. It is also known as very large G-protein coupled receptor 1 because it is 6300 residues long. It contains a C-terminal 7-transmembrane receptor domain, whereas the large N-terminal segment (5900 residues) includes 35 calcium binding Calx-beta domains, and 6 EAR domains.

Clinical significance

Mutations in this gene are associated with Usher syndrome 2 and familial febrile seizures.
