RESUMO
Ste4- mutants of Schizosaccharomyces pombe are unable to undergo both mating and meiosis. We have cloned the ste4+ gene and its cDNA. The gene encodes a 264 amino acid protein with a typical leucine zipper motif homologous with the jun family. However, unlike the jun family, this protein does not have a typical basic region that precedes the leucine zipper. The transcription of this gene absolutely depends on the ste11+ gene and increases several fold upon nitrogen starvation, a general signal for sexual differentiation. Whereas ste4+ is essential for mating and meiosis, its overexpression inhibits these processes.
