Predicted to enable protein N-terminus binding activity; protein homodimerization activity; and structural molecule activity. Predicted to be involved in negative regulation of epidermal growth factor-activated receptor activity and protein transport to vacuole involved in ubiquitin-dependent protein catabolic process via the multivesicular body sorting pathway. Predicted to act upstream of or within protein transport. Located in mitochondrion. Is expressed in several structures, including central nervous system; extraembryonic component; and lung. Orthologous to human VPS25 (vacuolar protein sorting 25 homolog). [provided by Alliance of Genome Resources, Apr 2022]
