CC   -!- FUNCTION: The sexual inducer is a glycoprotein synthesized and released
CC       by sexual males at about the time they release sperm packets. It is one
CC       of the most potent biological effector molecules known: it exhibits
CC       full effectiveness in converting asexually growing males and females to
CC       the sexual pathway at about 10(-7) m.
