High impact information on SPCC191.13

  • Here we show that the Rep2 zinc finger protein is an essential component of the active Res2-Cdc10 transcriptional regulator complex and likely to play a role in the control of cell cycle 'start'. Our data suggest that Rep2 is a transcriptional activator subunit which interacts with the MCB binding subunit complex formed by Res2 and Cdc10 [1].
  • On the basis of these observations, we speculate that Map1 may be a transcriptional regulator of cell-type-specific genes similar to S. cerevisiae MCM1, whose activity is modulated by the oil and alpha2 mating-type gene products [2].
  • In the fission yeast Schizosaccharomyces pombe, the "start" of the cell cycle is controlled by the two functionally redundant transcriptional regulator complexes, Res1p-Cdc10p and Res2p-Cdc10p, that activate genes essential for the onset and progression of S phase [3].
  • As a transcriptional regulator p53 enhances the expression of proteins that control cellular proliferation [4].
  • Uptake of thiamine by Schizosaccharomyces pombe and its effect as a transcriptional regulator of thiamine-sensitive genes [5].

Biological context of SPCC191.13

  • This contrasts with transcriptional regulator families, that are primarily taxon-specific, indicating proteins controlling gene activation exhibit considerable sequence diversity across the eukaryotic domain [6].

Analytical, diagnostic and therapeutic context of SPCC191.13

  • Mutants lacking this transcriptional regulator (which we have named ace2+) show a severe cell separation defect, hyphal growth being observed [7].
