Describe the basic signal-transduction pathway used for mating in yeast?

Answer 1

In the yeast signal transduction pathway, after both types of mating cells have released the mating factors and the factors have bound to specific receptors on the correct cells binding induces changes in the cells that lead to cell fusion.

Answer 2

In yeast, the mating signal transduction pathway is initiated when a mating factor binds to a G-protein-coupled receptor on the mating cell membrane. This activates a downstream signaling cascade involving protein kinases that ultimately lead to changes in gene expression and cell cycle progression to facilitate mating with a partner cell. The pathway culminates in the formation of a mating projection (shmoo) towards a partner cell for fusion and genetic recombination.
