GNG4 (G Protein Subunit Gamma 4) is a gamma subunit of heterotrimeric G proteins expressed predominantly in brain and testis. GNG4 forms Gβγ complexes that regulate neuronal signaling pathways including ion channel modulation and second messenger production. In the brain, GNG4 is involved in synaptic transmission and plasticity. GNG4 expression is downregulated in Alzheimer's disease and certain cancers, making it a potential biomarker and therapeutic target.
GNG4 encodes the G protein gamma 4 subunit, expressed predominantly in the retina and brain. It plays a role in phototransduction and GPCR-mediated signaling in neuronal tissues.
High expression in retina and brain. Important for visual signal transduction and synaptic function.
