Derlin 1 is a channel-like protein found in the endoplasmic reticulum (ER) membrane. It is specifically required for the degradation of misfolded ER luminal proteins. Derlin 1 participates in the transfer of misfolded proteins from the ER to the cytosol, where they are destroyed by the proteasome in a ubiquitin-dependent manner. It may act by forming a channel that allows the retrotranslocation of misfolded proteins into the cytosol and then transferring them to the ATPase VCP complex, which translocates and ubiquitinates misfolded proteins.
In the case of infection by cytomegaloviruses, derlin 1 plays a central role in 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. Derlin 1 also participates in the degradation of misfolded cytomegalovirus US2 protein.
Endoplasmic reticulum; multi pass membrane protein.
ab93341 stained HeLa cells. The cells were 100% methanol fixed for 5 minutes at -20°C and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1hour at room temperature to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab93341 at 5µg/ml) overnight at +4°C. The secondary antibody (pseudo-colored green) was Goat Anti-Rabbit IgG H&L (Alexa Fluor® 488) preadsorbed (ab150081) used at a 1/1000 dilution for 1hour at room temperature. Alexa Fluor® 594 WGA was used to label plasma membranes (pseudo-colored red) at a 1/200 dilution for 1hour at room temperature. DAPI was used to stain the cell nuclei (pseudo-colored blue) at a concentration of 1.43µM for 1hour at room temperature.
