Regulator G protein Signaling (RGS) proteins are critical components of the intracellular signaling pathways and amplitude of GPCR signaling. Another signaling pathway related to RGS4 involves the regulation of the immune response. Senese, N.B., et al., Regulator of G-Protein Signaling (RGS) Protein Modulation of Opioid Receptor Signaling Hepler, Cellular regulation of RGS proteins: modulators and integrators of G protein signaling.

When it comes to signal transduction, cellular context matters. to scaffold various kinases and modulate downstream signaling pathways. can be activated by ligands and initiate signaling cascades. , sustained signaling responses from intracellular compartments can be regulated by the kinetics of signaling Compartmentalized GPCR Signaling from Intracellular Membranes.

bound to these interaction partners available today do not reveal a clear conformational basis for signaling

Committee Sponsors GPCR Retreat Program < Back to schedule Unveiling Non-Canonical Functions for Gαq Signaling During this period and her doctoral thesis, she has deepened the regulatory mechanisms of GPCR signaling characterization of proteins that act at the level of G proteins and which are part of a multimolecular signaling complex (AGS, de “Activators of G-protein signaling). Ribas has characterized the existence of a new signaling pathway with a relevant role in cardiac hypertrophy
