Protein

Rab GDP-dissociation inhibitor

Gene

GDI1

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

Functioni

Regulates the GDP/GTP exchange reaction of SEC4 by inhibiting the dissociation of GDP from it, and the subsequent binding of GTP to SEC4. Plays an essential role in the yeast secretory pathway.1 Publication

Miscellaneous

Present with 7280 molecules/cell in log phase SD medium.1 Publication
