CC -!- FUNCTION: The active factor is excreted into the culture medium by CC haploid cells of the A mating type and acts on cells of the opposite CC mating type (type alpha). It mediates the conjugation process between CC the two types by inhibiting the initiation of DNA synthesis in type CC alpha cells and synchronizing them with type A. CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000305}; Lipid-anchor CC {ECO:0000305}; Cytoplasmic side {ECO:0000305}.
