In addition, RGS proteins have the additional function of increasing the rate of GTP-GDP exchange at GPCRs, (i.e., as a sort of co-GEF) further contributing to the time resolution of GPCR signaling.
Ademais, as proteínas RGS teñen a función adicional de incrementar o grao de intercambio GTP-GDP no GPCRs, (é dicir, un tipo de co-GEF) contribuíndo adicionalmente ao tempo de resolución da sinalización do GPCR.
