Summary: Predicted to enable ATP hydrolysis activity and protein homodimerization activity. Involved in late endosomal microautophagy; multivesicular body assembly; and viral budding from plasma membrane. Acts upstream of or within several processes, including canonical Wnt signaling pathway; establishment of blood-brain barrier; and potassium ion transport. Located in cytosol. Is expressed in central nervous system; head; and migrating neural crest. Orthologous to human VPS4B (vacuolar protein sorting 4 homolog B). [provided by Alliance of Genome Resources, Nov 2024]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
