Predicted to enable ATPase binding activity and protein self-association. Involved in negative regulation of VCP-NPL4-UFD1 AAA ATPase complex assembly. Predicted to be located in Golgi membrane; plasma membrane; and smooth endoplasmic reticulum membrane. Predicted to be active in endoplasmic reticulum membrane. Predicted to be anchored component of membrane. Orthologous to human SVIP (small VCP interacting protein). [provided by Alliance of Genome Resources, Apr 2022]
