**Background of Regulator of G-protein Signaling 11 (RGS11)**
Regulator of G-protein Signaling 11 (RGS11) belongs to the RGS protein family, a group of GTPase-activating proteins (GAPs) that negatively regulate G-protein-coupled receptor (GPCR) signaling by accelerating the hydrolysis of GTP bound to Gα subunits, thereby terminating downstream signaling. RGS11 is part of the R7 subfamily (alongside RGS6. RGS7. and RGS9), characterized by a conserved RGS domain and a G-protein gamma-like (GGL) domain that binds to Gβ5 subunits, forming functional complexes critical for stability and membrane targeting.
RGS11 is predominantly expressed in the nervous system, particularly in retinal bipolar cells and specific brain regions, where it modulates synaptic transmission and visual signal processing. Studies highlight its role in regulating metabotropic glutamate receptor (mGluR6) signaling in the retina, essential for ON-bipolar cell responses to light. Dysregulation of RGS11 has been linked to visual deficits, neurodegenerative disorders, and cancer progression, with evidence suggesting tumor-suppressive roles in certain contexts.
Recombinant RGS11 protein is used to dissect GPCR pathway dynamics, screen for modulators of G-protein signaling, and explore therapeutic strategies targeting RGS-Gβ5 interactions. Its structural and functional insights continue to advance understanding of neurophysiology and disease mechanisms.
