In yeast signal transduction, a yeast cell releases a mating factor, which:

#Unit 4. Cell Communication and Cell Signaling
  1. acts back on the same cell that secreted the mating factor, changing its development

  2. passes through the membranes of neighboring cells, binds to DNA, and initiates transcription

  3. binds to receptors on the membranes of other types of yeast cells

  4. diffuses through the membranes of distant cells, causing them to produce factors that initiate long-distance migrations
