About GNAT2

Cytogenetic location: 1p13.3 Genomic coordinates (GRCh38): 1:109,603,091-109,619,616 (from NCBI)

This gene has 3 transcripts (splice variants), 255 orthologues, 15 paralogues and is associated with 4 phenotypes. Biased expression in testis (RPKM 1.0), brain (RPKM 0.1) and 10 other tissues.

Summary

Transducin is a 3-subunit guanine nucleotide-binding protein (G protein) which stimulates the coupling of rhodopsin and cGMP-phoshodiesterase during visual impulses. The transducin alpha subunits in rods and cones are encoded by separate genes. This gene encodes the alpha subunit in cones. [provided by RefSeq, Jul 2008]
