An RGS subfamily including RGS6, -7, -9, and -11, which contain a characteristic Ggamma -like domain, also has the unique ability to interact with the G protein beta subunit Gbeta(5). Here, we examined the behavior of Gbeta(5), RGS7, RGS9, and Galpha in tissue extracts using immunoprecipitation and conventional chromatography. Native Gbeta(5) and RGS7 from brain, as well as photoreceptor-specific Gbeta(5)L and RGS9, always co-purified as tightly associated dimers, and neither RGS-free Gbeta(5) nor Gbeta(5)-free RGS could be detected. Co-expression in COS-7 cells of Gbeta(5) dramatically increased the protein level of RGS7 and vice versa, indicating that cells maintain Gbeta(5):RGS stoichiometry in a manner similar to Gbetagamma complexes. This mechanism is non-transcriptional and is based on increased protein stability upon dimerization. Thus, analysis of native Gbeta(5)-RGS and their coupled expression argue that in vivo, Gbeta(5) and Ggamma-like domain-containing RGSs only exist as heterodimers. Native Gbeta(5)-RGS7 did not co-precipitate or co-purify with Galpha(o) or Galpha(q); nor did Gbeta(5)L-RGS9 with Galpha(t). However, in transfected cells, RGS7 and Gbeta(5)-RGS7 inhibited Galpha(q)-mediated Ca(2+) response to muscarinic M3 receptor activation. Thus, Gbeta(5)-RGS dimers differ from other RGS proteins in that they do not bind to Galpha with high affinity, but they can still inhibit G protein signaling."xsd:string |
