WebMar 1, 2013 · Pheromones are recognized by specific receptors expressed on the surface of cells of the opposite mating type and this binding stimulates the activation of receptor-associated heterotrimeric G-proteins, which in turn promote the activation of a conserved mitogen-activated protein kinase (MAPK) module. WebNov 26, 2004 · The pheromone receptors activate a G protein heterotrimer consisting of an α subunit (Gpa1) and a βγ subunit dimer (Ste4-Ste18). Upon activation, the G protein subunits dissociate, and the signal is then transmitted and amplified through multiple effector proteins that bind to Gβγ.
