Ras GTPase-activating protein regulation of actin cytoskeleton and hyphal polarity in Aspergillus nidulans.

Eukaryotic cell - 1 Jan 2008

Abstract excerpt

Aspergillus nidulans gapA1, a mutation leading to compact, fluffy colonies and delayed polarity establishment, maps to a gene encoding a Ras GTPase-activating protein. Domain organization and phylogenetic analyses strongly indicate that GapA regulates one or more "true" Ras proteins. A gapADelta strain is viable. gapA colonies are more compact than gapA1 colonies and show reduced conidiation. gapADelta strains...
