Predicted to enable beta-3 adrenergic receptor binding activity. Involved in negative regulation of cold-induced thermogenesis. Acts upstream of or within several processes, including fat pad development; negative regulation of adenylate cyclase-activating adrenergic receptor signaling pathway; and negative regulation of locomotion involved in locomotory behavior. Predicted to be located in lysosome and membrane. Predicted to be active in endosome and plasma membrane. Is expressed in central nervous system; liver; lung; olfactory epithelium; and retina nuclear layer. Orthologous to human ARRDC3 (arrestin domain containing 3).
