Predicted to be involved in several processes, including cellular response to interferon-beta; defense response to other organism; and positive regulation of osteoblast differentiation. Predicted to be located in early endosome membrane; late endosome membrane; and lysosomal membrane. Predicted to be active in plasma membrane. Is expressed in alimentary system; epidermis; liver; and testis. Human ortholog(s) of this gene implicated in COVID-19; adenosquamous gallbladder carcinoma; and gallbladder adenocarcinoma. Orthologous to human IFITM1 (interferon induced transmembrane protein 1); IFITM2 (interferon induced transmembrane protein 2); and IFITM3 (interferon induced transmembrane protein 3).
