Enables ATP hydrolysis activity; adenyl ribonucleotide binding activity; and identical protein binding activity. Involved in endoplasmic reticulum to Golgi vesicle-mediated transport; positive regulation of ubiquitin-dependent protein catabolic process; and regulation of synapse organization. Located in cytosol and endoplasmic reticulum. Part of VCP-NPL4-UFD1 AAA ATPase complex and VCP-NSFL1C complex. Is active in glutamatergic synapse. Human ortholog(s) of this gene implicated in several diseases, including Charcot-Marie-Tooth disease type 2Y; Paget's disease of bone; amyotrophic lateral sclerosis type 14; inclusion body myopathy with early-onset Paget disease of bone with or without frontotemporal dementia 1; and inclusion body myositis. Orthologous to human VCP (valosin containing protein). [provided by Alliance of Genome Resources, Apr 2022]
