GNG3 (G Protein Subunit Gamma 3) is a gamma subunit of heterotrimeric G proteins that combines with Gβ subunits to form functional Gβγ complexes. GNG3 is primarily expressed in brain, particularly in the olfactory bulb and hippocampus. The Gβγ complex derived from GNG3 modulates various effectors including ion channels, adenylyl cyclases, and phospholipases. GNG3 plays roles in olfactory signal transduction, synaptic plasticity, and neuronal differentiation. Altered GNG3 expression is observed in neurodegenerative diseases and psychiatric disorders.
GNG3 encodes the G protein gamma 3 subunit, which partners with GNB subunits to form functional G beta-gamma dimers. These dimers regulate various effectors including ion channels, adenylyl cyclases, and phospholipases in neurons.
Expressed in brain, particularly in the hippocampus and cortex. Important for synaptic plasticity and memory formation.
