Schematics of the structures of the standard RGS domain containing proteins. Listed are the RGS domain containing proteins that act as GTPase activating proteins for Gαi and/or Gαq. Abbreviations include RBD, Ras Binding Domain; PDZ, Post Synaptic density Disc-large Zo-1; RGS, Regulator of G-protein Signaling; PTB, PhosphoTyrosine Binding domain; DEP; Dishevelled, Egl-10 and Pleckstrin domain, GoLoco (GPR domain); GGL; G protein Gamma-Like domain, DUF; Domain of Unknown Function; and TFIIA, Transcription Factor IIA domain. Predicted molecular weights (M.W.) of the different proteins are shown.
