Enables tumor necrosis factor-activated receptor activity. Involved in several processes, including cellular response to growth factor stimulus; cellular response to tumor necrosis factor; and response to lipopolysaccharide. Located in several cellular components, including neuronal cell body; perinuclear region of cytoplasm; and varicosity. Used to study visual epilepsy. Biomarker of Crohn's disease; myocardial infarction; sciatic neuropathy; and ureteral obstruction. Human ortholog(s) of this gene implicated in several diseases, including Parkinsonism; acne; bone disease (multiple); glomerulonephritis (multiple); and lung disease (multiple). Orthologous to human TNFRSF1B (TNF receptor superfamily member 1B). [provided by Alliance of Genome Resources, Apr 2022]
