Overview
Mermaid diagram (expand to render)
The RGS2 gene encodes Regulator of G Protein Signaling 2, a GTPase-activating protein that accelerates the intrinsic GTP hydrolysis rate of Galpha subunits, thereby terminating G protein-coupled receptor signaling.
Function
RGS2 is a key negative regulator of G protein signaling:
GTPase acceleration: GAP activity speeds Gα subunit inactivation
Signal termination: Limits duration of GPCR signaling
Specificity: Preferentially targets Gαq and Gαs subunits
Non-GAP functions: Scaffold for protein interactions
Regulation: Expression induced by cAMP, calcium, stressRGS2 is an immediate-early gene induced by neuronal activity.
Disease Associations
Alzheimer's Disease
- RGS2 expression altered in AD brain
- Modulates amyloidogenic [APP](/entities/app-protein) processing
- Synaptic plasticity regulation
Parkinson's Disease
- Dopamine receptor signaling modulation
