Predicted to enable calcium ion binding activity; identical protein binding activity; and wide pore channel activity. Involved in apoptotic process; circadian rhythm; and response to ethanol. Located in cytoplasmic vesicle and extracellular space. Used to study asthma; colon carcinoma; and glomerulonephritis. Biomarker of membranoproliferative glomerulonephritis. Human ortholog(s) of this gene implicated in several diseases, including Crohn's disease; familial hemophagocytic lymphohistiocytosis 2; human immunodeficiency virus infectious disease; multiple sclerosis; and non-Langerhans-cell histiocytosis. Orthologous to human PRF1 (perforin 1). [provided by Alliance of Genome Resources, Apr 2022]
