Anti-Interferon-α Receptor, Type I, Subunit I (Ser535,539) Antibody

Interferons are widely used therapeutic agents because of their anti tumor and antiviral effects and because of their modulatory effects on the immune system (Biron, 2001; Kirkwood, 2002). These cytokines produce their effects by binding to the Type 1 Interferon-α Receptor (IFNAR1). Down regulation of this receptor plays a key role in determining the magnitude and duration of cytokine signaling. This down regulation is thought to be influenced by phosphorylation of Serine-535 and Ser-539 in the IFNAR1 (Kumar et al., 2003).
