After nucleotide exchange, the G-protein alpha subunit dissociates from the beta-gamma complex (reviewed in Malbon, 2004). The G-alpha t2 and o subunits activate signaling through PDEs and promote the release of intracellular calcium (Ahumada et al, 2002; reviewed in Wang and Malbon, 2004) while the beta-gamma complex recruits PLC and initiates phosphoinositol signaling (reviewed in Smrcka, 2008), although both components may also play other roles.
