This family contains a number of ubiquitin-like proteins: SUMO (smt3 homologue) (see Swiss:Q02724), Nedd8 (see Swiss:P29595), Elongin B (see Swiss:Q15370), Rub1 (see Swiss:Q9SHE7), and Parkin (see Swiss:O60260). A number of them are thought to carry ...
This family contains a number of ubiquitin-like proteins: SUMO (smt3 homologue) (see Swiss:Q02724), Nedd8 (see Swiss:P29595), Elongin B (see Swiss:Q15370), Rub1 (see Swiss:Q9SHE7), and Parkin (see Swiss:O60260). A number of them are thought to carry a distinctive five-residue motif termed the proteasome-interacting motif (PIM), which may have a biologically significant role in protein delivery to proteasomes and recruitment of proteasomes to transcription sites [5].
Ubiquitin fusion degradation protein UFD1, N-terminal subdomain 2

Post-translational ubiquitin-protein conjugates are recognised for degradation by the ubiquitin fusion degradation (UFD) pathway. Several proteins involved in this pathway have been identified [1]. UFD1 is a 40kD protein that is essential for vegetative cell viability [1]. The human UFD1 gene is expressed at high levels during embryogenesis, especially in the eyes and in the inner ear primordia and is thought to be important in the determination of ectoderm-derived structures, including neural crest cells. In addition, this gene is deleted in the CATCH-22 (cardiac defects, abnormal facies, thymic hypoplasia, cleft palate and hypocalcaemia with deletions on chromosome 22) syndrome. This clinical syndrome is associated with a variety of developmental defects, all characterised by microdeletions on 22q11.2. Two such developmental defects are the DiGeorge syndrome OMIM:188400, and the velo-cardio- facial syndrome OMIM:145410. Several of the abnormalities associated with these conditions are thought to be due to defective neural crest cell differentiation [2]. UFD1 is composed of an N-terminal conserved region (UT3) and a C-terminal disordered region (UT6) which contains the binding sites for both Npl4 and Cdc48 [3, 4]. UFD1 N-terminal domain contains the binding site for ubiquitin [3, 4] and has a similar structure to p97. It is made of two subdomains [5]. This entry corresponds to the second subdomain of UFD1 UT3 which has a mixed alpha/beta roll structure [5].

Npl4 is part of the heterodimer UN along with Ufd1 which is involved in the recruitment of p97, an AAA ATPase, for tasks involving the ubiquitin pathway. Npl4 has a ubiquitin-like domain which has within its structure a beta-grasp fold with a helical ...

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 Pfam:PF00004 is a substrate 185-residue recognition domain [1].
