RGS6 (Regulator of G Protein Signaling 6): RGS6 is a member of the RGS family that plays a vital role in regulating G protein-coupled receptor (GPCR) signaling pathways. It accelerates the GTPase activity of G protein α subunits, effectively switching off GPCR signaling and serving as a key modulator of signal transduction. This regulation is crucial for various physiological processes, including sensory perception, cardiovascular regulation, and central nervous system functions. By precisely modulating GPCR signaling, RGS6 helps manage cellular responses to external stimuli.
