About GNB1

Cytogenetic location: 1p36.33 Genomic coordinates (GRCh38): 1:1,785,286-1,891,087 (from NCBI)

This gene has 31 transcripts (splice variants), 226 orthologues, 4 paralogues and is associated with 5 phenotypes. Ubiquitous expression in brain (RPKM 145.4), small intestine (RPKM 87.2) and 25 other tissues.

Summary

Heterotrimeric guanine nucleotide-binding proteins (G proteins), which integrate signals between receptors and effector proteins, are composed of an alpha, a beta, and a gamma subunit. These subunits are encoded by families of related genes. This gene encodes a beta subunit. Beta subunits are important regulators of alpha subunits, as well as of certain signal transduction receptors and effectors. Alternative splicing results in multiple transcript variants.
