High impact information on FLO8

  • First, regulation via the MAPK pathway requires the transcription factors Ste12p/Tec1p, whereas cAMP-mediated activation requires a distinct factor, Flo8p [1].
  • In the final step, Flo8 and Mss11 directly promote association of RNA polymerase II with the STA1 promoter to activate STA1 expression [2].
  • PKA signals pseudohyphal growth, in part, by regulating Flo8-dependent expression of the cell surface flocculin Flo11 [3].
  • Deleting FLO8 in C. albicans blocked hyphal development and hypha-specific gene expression [4].
  • The Flo8 transcription factor is essential for hyphal development and virulence in Candida albicans [4].

Other interactions of FLO8

  • It is thought that the FLO8 gene encodes a transcriptional activator of the dominant flocculation gene FLO1 in Saccharomyces cerevisiae [10].
  • Moreover, the STA10 repression is suppressed completely or partially by the introduction of a single copy of the FLO8 or MSS11 genes [5].
  • Signaling pathway-responsive transcription factors such as Ste12, Tec1, and Flo8 are known to mediate filamentation-specific transcription [11].
  • Although inactivation of Hsl1 is sufficient to suppress the defect in filamentous growth caused by inactivation of Tec1 or Flo8, it is insufficient to promote filamentous growth in the absence of both factors [12].
  • We conclude that the Swe1 kinase modulates filamentous development under a broad spectrum of conditions and that its role is partially redundant with the Tec1 and Flo8 transcription factors [12].
