Enables cupric ion binding activity and mating pheromone activity. Involved in pheromone-dependent signal transduction involved in conjugation with cellular fusion. Located in extracellular region.
SGD Description
Alpha-factor mating pheromone made by alpha cells; interacts with mating type a cells to induce cell cycle arrest and other responses leading to mating; also encoded by MF(ALPHA)2, although MF(ALPHA)1 produces most alpha-factor; binds copper(II) ions
