Protein
Multivesicular body sorting factor 12
Gene
MVB12, YGR206W, G7740
Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c) (Baker's yeast)
Status
Reviewed - Annotation score: 5 out of 5 - Experimental evidence at protein leveli

Functioni

Component of the ESCRT-I complex, a regulator of vesicular trafficking process. Binds to ubiquitinated cargo proteins and is required for the sorting of endocytic ubiquitinated cargos into multivesicular bodies (MVBs). Appears to be involved in cargo sorting and release of the ESCRT-I complex from the MVBs.1 Publication
