In S. pombe the gti1 protein promotes the onset of gluconate uptake upon glucose starvation [1]. In S. pombe the Pac2 protein controls the onset of sexual development, by inhibiting the expression of ste11, in a pathway that is independent of the cAMP cascade [2].

1: Onset of gluconate-H+ symport in Schizosaccharomyces pombe is regulated by the kinases Wis1 and Pka1, and requires the gti1+ gene product. Caspari T; J Cell Sci. 1997;110:2599-2608. PMID:9372449

2: Schizosaccharomyces pombe pac2+ controls the onset of sexual development via a pathway independent of the cAMP cascade. Kunitomo H, Sugimoto A, Wilkinson CR, Yamamoto M; Curr Genet. 1995;28:32-38. PMID:8536311
