Protein
Vacuolar protein sorting-associated protein VTA1
Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c)
Function
Has a role in the formation of the multivesicular body (MVB). Required for the sorting of lipids to form intralumenal vesicles and for fluid-phase transport to the vacuole. Required for sorting the plasma membrane proteins STE2 and STE3 into the MVB. Acts a cofactor of VSP4, promotes the oligomerization of VPS4 and stimulates its ATPase activity by 6- to 8-fold.
Similarity
Belongs to the VTA1 family.
