Predicted to enable protease binding activity. Predicted to be involved in several processes, including ERAD pathway; negative regulation of retrograde protein transport, ER to cytosol; and protein retention in ER lumen. Predicted to be located in endoplasmic reticulum. Predicted to be active in endoplasmic reticulum lumen. Is expressed in several structures, including alimentary system; central nervous system; genitourinary system; respiratory system; and sensory organ. Orthologous to human OS9 (OS9 endoplasmic reticulum lectin). [provided by Alliance of Genome Resources, Apr 2022]
