Description_x000D_ General description_x000D_ 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._x000D_ Immunogen_x000D_ 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._x000D_ Application_x000D_ Anti-Derlin-3 antibody produced in rabbit has been used in immunoblotting, immunoprecipitation, and immunofluorescence._x000D_ Physical form_x000D_ Solution in 0.01 M phos­phate buffered saline, pH 7.4, containing 15 mM sodium azide._x000D_ Disclaimer_x000D_ Unless otherwise stated in our catalog or other company documentation accompanying the product(s), our products are intended for research use only and are not to be used for any other purpose, which includes but is not limited to, unauthorized commercial uses, in vitro diagnostic uses, ex vivo or in vivo therapeutic uses or any type of consumption or application to humans or animals._x000D_ Biochem/physiol Actions_x000D_ 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.
