Introduction
CUE Domain Containing 1, also known as CUEDC1, contains one CUE domain. This domain is structurally similar to the ubiquitin-binding UBA domain and forms a domain-swapped dimer that enhances its interaction with ubiquitin, leading to high-affinity binding. CUE domains are found in proteins involved in various cellular processes, such as protein sorting and the degradation of misfolded proteins in the endoplasmic reticulum.
Description
Recombinant human CUEDC1 protein was expressed in E. coli and purified to a single, non-glycosylated polypeptide chain. This protein consists of 409 amino acids (residues 1-386), including a 23 amino acid His-tag fused to the N-terminus, and has a molecular weight of 44.6 kDa. Purification was achieved using proprietary chromatographic techniques.
Physical Appearance
A clear solution that has been sterilized by filtration.
Formulation
This CUEDC1 protein solution has a concentration of 0.25 mg/ml and is supplied in a buffer consisting of 20 mM Tris-HCl (pH 8.0), 0.15 M NaCl, 20% glycerol, and 1 mM DTT.
Stability
For short-term storage (up to 2-4 weeks), the product can be stored at 4°C. For long-term storage, it is recommended to store the product frozen at -20°C. To further enhance stability during long-term storage, adding a carrier protein like HSA or BSA (0.1%) is advisable. Repeated freezing and thawing of the product should be avoided.
Purity
The purity of this product is greater than 85% as determined by SDS-PAGE analysis.
Synonyms
CUE Domain Containing 1, CUE Domain-Containing Protein 1.
