Predicted to enable calcium-dependent protein binding activity. Predicted to be involved in positive regulation of viral budding via host ESCRT complex; protein targeting; and ubiquitin-dependent protein catabolic process via the multivesicular body sorting pathway. Predicted to act upstream of or within protein transport. Predicted to be located in endosome membrane; midbody; and plasma membrane. Predicted to be part of ESCRT I complex. Is expressed in several structures, including central nervous system; cranium; and retina. Orthologous to human VPS37B (VPS37B subunit of ESCRT-I). [provided by Alliance of Genome Resources, Apr 2022]
