Predicted to enable misfolded protein binding activity; signal recognition particle binding activity; and ubiquitin-specific protease binding activity. Predicted to be involved in cellular protein metabolic process; endoplasmic reticulum unfolded protein response; and negative regulation of retrograde protein transport, ER to cytosol. Predicted to be located in endoplasmic reticulum and membrane. Predicted to be integral component of membrane. Predicted to be part of Hrd1p ubiquitin ligase ERAD-L complex. Predicted to be integral component of endoplasmic reticulum membrane. Is expressed in several structures, including central nervous system; genitourinary system; liver; sensory organ; and spleen. Orthologous to human DERL3 (derlin 3). [provided by Alliance of Genome Resources, Apr 2022]
