Cell division protein 48 (CDC48) N-terminal domain
SMART accession number:SM01073
Description: 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 N-terminus. The VAT-N domain found in AAA ATPases is a substrate 185-residue recognition domain (PUBMED:10531028).
Interpro abstract (IPR003338):

This entry represents the amino-terminal subdomain.

The CDC48 N-terminal domain is a protein domain found in AAA ATPases including cell division protein 48 (CDC48), VCP-like ATPase (VAT) and N-ethylmaleimide sensitive fusion protein. It is a substrate recognition domain which binds polypeptides, prevents protein aggregation, and catalyses refolding of permissive substrates. It is composed of two equally sized subdomains. The amino-terminal subdomain forms a double-psi beta-barrel whose pseudo-twofold symmetry is mirrored by an internal sequence repeat of 42 residues. The carboxy-terminal subdomain forms a novel six-stranded beta-clam fold [ (PUBMED:10531028) ]. Together these subdomains form a kidney-shaped structure.
