Predicted to enable lipid binding activity and ubiquitin binding activity. Predicted to be involved in several processes, including endosome to lysosome transport via multivesicular body sorting pathway; receptor catabolic process; and virus maturation. Predicted to be located in several cellular components, including Golgi apparatus; centrosome; and nucleoplasm. Predicted to be part of ESCRT I complex. Predicted to be active in cytosol. Orthologous to human MVB12A (multivesicular body subunit 12A). [provided by Alliance of Genome Resources, Apr 2022]
