Protein

Arf guanine nucleotide exchange factor SYT1

Gene

SYT1

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

Guanine nucleotide exchange factor for Arf GTPases, stimulating the nucleotide exchange from the GDP-bound to the GTP-bound form. Catalyzes both the GDP release by and the GTP binding to ARF2. Has no exhange activity on Rab GTPases. Involved in vesicular transport.1 Publication

Miscellaneous

Present with 279 molecules/cell in log phase SD medium.1 Publication

Enzyme regulationi

Inhibited by brefeldin A.
