immunoprecipitation (IP): 5-10 μg using extract of HEK-293T cells expressing recombinant human Derlin-3 indirect immunofluorescence: 10-20 μg/mL using human HeLa cells western blot: 2-5 μg/mL using whole extract of HEK-293T cells expressing recombinant human Derlin-3
Derlin-3 is a mammalian homologues of yeast Der1p, a transmembrane protein required for yeast endoplasmic reticulum (ER)-associated degradation (ERAD). Derlin 3 is encoded by the gene mapped to human chromosome 22q11.23. It is expressed in the ER and is a member of the derlin protein family.
免疫原
synthetic peptide corresponding to amino acid residues 192-205 of human Derlin-3, conjugated to KLH. The corresponding sequence differs by 3 amino acids in mouse and 2 amino acids in rat.
應用
Anti-Derlin-3 antibody produced in rabbit has been used in immunoblotting, immunoprecipitation, and immunofluorescence.
生化/生理作用
Derlin-3 is involved in the degradation of misfolded glycoproteins in the ER. Derlin-3 shares ~30% sequence identity with Derlin-1 and spans the lipid bilayer of the ER four times, showing structural similarity to Derlin-1. It is a component of the mammalian ER-associated degradation (ERAD) mechanism and is upregulated by unfolded protein response (UPR). Overexpression of this gene leads to increase in degradation of misfolded glycoprotein, whereas its knockdown blocks degradation. Derlin-3 also interacts with the mammalian orthologs of the yeast Hrd1p/Hrd3p ubiquitin-ligase complex.

Polypeptides that fail to pass quality control in the endoplasmic reticulum (ER) are dislocated from the ER membrane to the cytosol where they are degraded by the proteasome. Derlin-1, a member of a family of proteins that bears homology to

Proteins that are unfolded or misfolded in the endoplasmic reticulum (ER) must be refolded or degraded to maintain the homeostasis of the ER. Components of both productive folding and ER-associated degradation (ERAD) mechanisms are known to be up-regulated by the
The thrombospondin (Thbs) family of secreted matricellular proteins are stress- and injury-induced mediators of cellular attachment dynamics and extracellular matrix protein production. Here we show that Thbs1, but not Thbs2, Thbs3 or Thbs4, induces lethal cardiac atrophy when overexpressed. Mechanistically
