About GABBR2

Cytogenetic location: 9q22.33 Genomic coordinates (GRCh38): 9:98,288,109-98,708,935 (from NCBI)

This gene has 12 transcripts (splice variants), 241 orthologues, 2 paralogues and is associated with 5 phenotypes. Restricted expression toward brain (RPKM 33.5).

Summary

The multi-pass membrane protein encoded by this gene belongs to the G-protein coupled receptor 3 family and GABA-B receptor subfamily. The GABA-B receptors inhibit neuronal activity through G protein-coupled second-messenger systems, which regulate the release of neurotransmitters, and the activity of ion channels and adenylyl cyclase. This receptor subunit forms an active heterodimeric complex with GABA-B receptor subunit 1, neither of which is effective on its own. Allelic variants of this gene have been associated with nicotine dependence.[provided by RefSeq, Jan 2010]
