How signaling is involved in ensuring that yeast cells fuse only with cells of the opposite mating type?

#Unit 4. Cell Communication and Cell Signaling
  1. The two cells of opposite mating type (a and alpha) each secrete a certain signaling molecule, which can only be bound by receptors carried on cells of the opposite mating type. Thus, the a mating factor cannot bind to another a cell and cause it to grow toward the first a cell. Only an alpha cell can “receive” the signaling molecule and respond by directed growth.
  2. The two cells of opposite mating type (a and alpha) each secrete a certain signaling molecule, which can only be bound by receptors carried on cells of the same mating type. Thus, the a mating factor can bind to another a cell and cause it to grow toward the first a cell.
  3. The two cells of opposite mating type (a and alpha) each proteins attached to the plasma membrane of one cell can interact directly with cell-surface receptors on adjacent cells. Thus, the a mating factor can directly bind to another a cell and cause it to grow.
  4. The two cells of opposite mating type (a and alpha) each respond to substances that they themselves release.
