RT cerevisiae.";
RL J. Biochem. 82:1681-1687(1977).
CC -!- FUNCTION: The active factor is excreted into the culture medium by
CC haploid cells of the alpha mating type and acts on cells of the
CC opposite mating type (type A). It mediates the conjugation process
CC between the two types by inhibiting the initiation of DNA synthesis in
CC type a cells and synchronizing them with type alpha.
CC -!- DOMAIN: The mating factor alpha-1 precursor is identical in S.italicus,
CC S.uvarum and S.cerevisiae, except for the number of tandem repeat
CC units: 5, 3 and 4 respectively.
