Predicted to enable several functions, including phosphatidylinositol-3,4-bisphosphate binding activity; phospholipid binding activity; and protein homodimerization activity. Predicted to be involved in several processes, including Golgi to plasma membrane transport; negative regulation of protein localization to cell surface; and regulation of cellular protein metabolic process. Predicted to act upstream of or within several processes, including cholesterol homeostasis; low-density lipoprotein particle clearance; and positive regulation of protein localization. Predicted to be located in cytosol; endosome; and nucleoplasm. Predicted to be part of Cul2-RING ubiquitin ligase complex. Predicted to be active in endosome. Orthologous to human COMMD1 (copper metabolism domain containing 1). [provided by Alliance of Genome Resources, Apr 2022]
