Predicted to enable protein homodimerization activity and structural molecule activity. Predicted to be involved in protein transport to vacuole involved in ubiquitin-dependent protein catabolic process via the multivesicular body sorting pathway. Predicted to act upstream of or within multivesicular body sorting pathway and protein transport. Predicted to be located in cytoplasm. Predicted to be part of ESCRT II complex. Orthologous to human VPS25 (vacuolar protein sorting 25 homolog).
