Protein

Vacuolar membrane protein PEP3

Gene

PEP3

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

Required for vacuolar biogenesis and for trafficking of hydrolase precursors to the vacuole. Mediates transport at the vacuolar membrane where it may be responsible for tethering transport vesicles on the target membranes. Acts as component of the HOPS complex that acts during the docking stage of vacuole fusion. HOPS is an effector for the vacuolar Rab GTPase YPT7 and is required for vacuolar SNARE complex assembly. It remains bound to SNARE complexes after vacuole fusion.2 Publications

Miscellaneous
