Allregulin (ARLN) is a protein which in humans is encoded by the C4orf3 gene. ARLN is a small ER transmembrane protein that regulates calcium homeostasis through SERCA (sarco-endoplasmic reticulum calcium ATPase). It is also known as C4orf3 and HCVFTP1 (hepatitis C virus F protein-transactivated protein 1).
