WebRegulator of G protein signaling (RGS) proteins are regulatory and structural components of G protein-coupled receptor complexes. RGS proteins are GTPase-activating proteins for Gi (see GNAI1; 139310) and Gq (see GNAQ; 600998) class G-alpha proteins.They accelerate transit through the cycle of GTP binding and hydrolysis and thereby accelerate signaling … GTPase-activating proteins or GTPase-accelerating proteins (GAPs) are a family of regulatory proteins whose members can bind to activated G proteins and stimulate their GTPase activity, with the result of terminating the signaling event. GAPs are also known as RGS protein, or RGS proteins, and … See more GAP are heavily linked to the G-protein linked receptor family. The activity of G proteins comes from their ability to bind guanosine triphosphate (GTP). Binding of GTP inherently changes the activity of the G proteins and … See more In general, GAPs tend to be pretty specific for their target G proteins. The exact mechanism of target specificity is not fully known, but it is likely that this specificity comes from a variety of factors. At the most basic level, GAP-to-G protein specificity may … See more While GAPs serve to regulate the G proteins, there is also some level of regulation of the GAPs themselves. Many GAPs have allosteric sites that serve as interfaces with … See more • GTPase-Activating+Proteins at the U.S. National Library of Medicine Medical Subject Headings (MeSH) See more EIF5 is a GTPase-activating protein. Furthermore, YopE is a protein domain that is a Rho GTPase-activating protein (GAP), which targets small GTPases such as RhoA, Rac1, and Rac2. Monomeric The GAPs that act … See more The importance of GAPs comes from its regulation of the crucial G proteins. Many of these G proteins are involved in cell cycling, and as … See more
