Background: IFN-alpha 12

Interferon-alpha 12 (IFN alpha -12) is a member of the type I interferon-alpha (IFN-alpha ) family (1). The members of the IFN-alpha family, also known as alpha leukocyte interferons, encompass a group of distinct but closely related proteins which share approximately 80% amino acid (aa) sequence identity and have a similar globular structure composed of five alpha-helices (1-3). IFN-alpha family members signal through a common set of cell surface receptor complex composed of IFN-alpha R2 and IFN-alpha R1 subunits (2). The mature extracellular domain (ECD) of mouse IFN alpha -12 is 166 aa. While IFNa-12 does not exist in humans, it closely resembles other murine members of the IFN-alpha family, such as sharing 88% and 86% sequence identity with IFN alpha -15 and IFN alpha -11 respectively. Murine IFN-alpha 12 differs from other members of the IFN-alpha family by its anti-proliferative function and in the inability of its expression to be regulated by viral infection (5).
