Gng2 Gene is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
GNG2 encodes the G protein subunit gamma 2 (Gγ2), a component of heterotrimeric G protein complexes that mediate cellular signaling throughout the nervous system.

Gγ2 forms heterodimers with Gβ subunits (primarily Gβ3, Gβ4, Gβ5) to create functional Gβγ complexes. These complexes modulate ion channel activity (GIRK channels, calcium channels), adenylyl cyclase, phospholipase C, and phosphoinositide 3-kinase. Critical for neuronal differentiation, synaptic transmission, circadian rhythm regulation, and sensory processing.
Alzheimer's Disease: Altered Gβγ signaling in hippocampal neurons.
Parkinson's Disease: Dysregulated G protein signaling in dopaminergic neurons.
Schizophrenia: Impaired G protein coupling affects neurotransmission.
Cancer: Altered cell proliferation and survival signaling.
