Description
The DCUN1 domain is an ~190-residue module found in the eukaryotic defective
in cullin neddylation (DCN) protein family, which includes:
- Yeast DCN1.
- Vertebrate DCN1-like protein 1.
- Vertebrate DCN1-like protein 2.
- Vertebrate DCN1-like protein 4.
Proteins of the DCN family may contribute to neddylation of cullin components
of SCF-type E3 ubiquitin ligase complexes, which are multi-protein complexes
required for polyubiquitination and subsequent degradation of target proteins
by the 26S proteasome
[1]. Although the DCUN1 domain function is unknown, it
has been suggested that it has features of a basic helix-loop-helix leucine
zipper (bHLH-ZIP) domain
[2].
The DCUN1 domain can be found in association with an UBA-like domain
[1].
The profile we developed covers the entire DCUN1 domain.
