Vacuolar-sorting protein BRO1

Gene

BRO1

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

Functioni

Class E VPS protein involved in concentration and sorting of cargo proteins of the multivesicular body (MVB) for incorporation into intralumenal vesicles. Fusion between endosomes and the vacuole will then target the cargo proteins to the vacuolar lumen. Acts as an adapter that recruits the DOA4 deubiquitinase to the endosomes, leading to deubiquitination of cargo proteins prior to the lumenal sequestration. Its association to the endosomes depends on SNF7 and its dissociation requires VPS4. Interacts functionally with the Pkc1p-mitogen-activated protein kinase pathway.6 Publications
