Entrez ID 2779
Gene name G protein subunit alpha transducin 1
Gene symbol GNAT1
Synonyms (NCBI Gene)
CSNB1GCSNBAD3GBT1GNATRHG1F
Chromosome 3
Chromosome location 3p21.31
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
