Protein

GTP-binding protein RHO3

Gene

RHO3

Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c) (Baker's yeast)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Plays an important role in cell growth. Required to keep the uninucleated state. May be involved in the organization of the cytoskeleton which affects microtubule functions. Most likely RHO3 and RHO4 of S.cerevisiae regulate partially overlapping but different pathways.1 Publication

Miscellaneous

Present with 5910 molecules/cell in log phase SD medium.1 Publication
