Protein
Suppressor protein STP22 of temperature-sensitive alpha-factor receptor and arginine permease
Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c)
Function
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). Mediates the association to the ESCRT-0 complex. Required for vacuolar targeting of temperature-sensitive plasma membrane proteins STE2 and CAN1.
Similarity
Belongs to the ubiquitin-conjugating enzyme family. UEV subfamily.
