A signal transduction process resulting in the relay, amplification or dampening of a signal generated in response to pheromone exposure in organisms that undergo conjugation with cellular fusion. An example of this process is found in Saccharomyces cerevisiae.

All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.

Any of a family of heterotrimeric GTP-binding and hydrolyzing proteins; they belong to a superfamily of GTPases that includes monomeric proteins such as EF-Tu and RAS. Heterotrimeric G-proteins consist of three subunits; the alpha subunit contains the guanine nucleotide binding site and possesses GTPase activity; the beta and gamma subunits are tightly associated and function as a beta-gamma heterodimer; extrinsic plasma membrane proteins (cytoplasmic face) that function as a complex to transduce signals from G protein-coupled receptors to an effector protein.

The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.

The heterodimer formed by the beta and gamma subunits of a heterotrimeric G protein, which dissociates from the alpha subunit upon guanine nuclotide exchange.

The part of a cell encompassing the cell cortex, the plasma membrane, and any external encapsulating structures.

A complex that forms at the cell cortex in response to pheromone treatment and is required for the polarized growth of haploid yeast cells towards a mating partner during yeast mating. In the yeast Saccharomyces cerevisiae, this complex consists of Cdc24p, Far1p, Ste4p (G-protein beta subunit) and Ste18p (G-protein gamma subunit).
