Gamma-aminobutyric acid B receptor, 1(GABA_B1), is aG-protein coupled receptorsubunit encoded by theGABBR1gene.

Function

GABA_B1is a receptor forGamma-aminobutyric acid.Upon binding, GABA_B1will produce a slow and prolonged inhibitory effect. GABA_B1is one part of a heterodimer, which is the GABA_Breceptor, consisting of it and the related GABA_B2protein. The GABA(B) receptor 1 gene is mapped to chromosome 6p21.3 within the HLA class I region close to the HLA-F gene. Susceptibility loci for multiple sclerosis, epilepsy, and schizophrenia have also been mapped in this region. Alternative splicing of this gene generates 4 transcript variants.

Interactions

GABBR1 has been shown tointeractwithATF4andGABBR2.
