High impact information on cdc42

  • Gene disruption of pak1+ establishes that, like cdc42+, pak1+ function is required for cell viability [1].
  • The cdc42 null phenotype is an arrest as small, round, dense cells [2].
  • While overexpression of either shk2 or cdc42 alone does not impair growth of wild type fission yeast cells, cooverexpression of the two genes is toxic and leads to highly aberrant cell morphology, providing evidence for functional interaction between Cdc42 and Shk2 proteins in vivo [3].
