DERL1 (human)

Overview
DERL1 Functional component of endoplasmic reticulum-associated degradation (ERAD) for misfolded lumenal proteins. May act by forming a channel that allows the retrotranslocation of misfolded proteins into the cytosol where they are ubiquitinated and degraded by the proteasome. May mediate the interaction between VCP and the degradation substrate. In case of infection by cytomegaloviruses, it plays a central role in the export from the ER and subsequent degradation of MHC class I heavy chains via its interaction with US11 viral protein, which recognizes and associates with MHC class I heavy chains. Also participates in the degradation process of misfolded cytomegalovirus US2 protein. Forms homo- and heterooligomers with DERL2 and DERL3; binding to DERL3 is poorer than that between DERL2 and DERL3. Interacts with AMFR, VIMP/SELS, SEL1L, SYVN1 and VCP, as well as with SEL1L-SYVN1 and VCP-VIMP protein complexes; this interaction is weaker than that observed between DERL2 and these complexes. Interacts with the cytomegalovirus US11 protein. Interacts with NGLY1 and YOD1. Does not bind to EDEM1. Interacts with RNF103. Up-regulated in response to endoplasmic reticulum stress via the ERN1-XBP1 pathway of the unfolded protein response (UPR). Ubiquitous. Belongs to the derlin family. 2 isoforms of the human protein are produced by alternative splicing. Note: This description may include information from UniProtKB.
