Involved in cardiac muscle cell differentiation. Predicted to be located in several cellular components, including bounding membrane of organelle; cell surface; and endoplasmic reticulum. Predicted to be part of protein-containing complex. Human ortholog(s) of this gene implicated in COVID-19; adenosquamous gallbladder carcinoma; and gallbladder adenocarcinoma. Orthologous to several human genes including IFITM3 (interferon induced transmembrane protein 3). [provided by Alliance of Genome Resources, Apr 2022]
