Predicted to enable ubiquitin binding activity. Predicted to be involved in positive regulation of ubiquitin-dependent endocytosis; protein transport to vacuole involved in ubiquitin-dependent protein catabolic process via the multivesicular body sorting pathway; and regulation of protein metabolic process. Located in cytosol. Orthologous to human VPS28 (VPS28 subunit of ESCRT-I). [provided by Alliance of Genome Resources, Apr 2022]
