Cell division protein 48, Cdc48, domain 2 This domain has a double psi-beta barrel fold and includes VCP-like ATPase and N-ethylmaleimide sensitive fusion protein N-terminal domains. Both the VAT and NSF N-terminal functional domains consist of two structural domains of which this is at the C terminus. The VAT-N domain found in AAA ATPases (<db_xref db="INTERPRO" dbkey="IPR003959"/>) is a substrate 185-residue recognition domain [<cite idref="PUB00007420"/>].
