Western blot of immunolabeling of DYKDDDDK Epitope Tag immunoprecipitate from HEK 93 cell transfected with 1. Mock, 2. IFNAR1 WT and 3. IFNAR1 S535A and S539A mutants. The labeling by the antibody is absent in the IFNAR1 Ser535 and Ser539 mutants. The labeling is blocked by the phosphopeptide used as antigen but not by the dephospho form of this peptide. (A= control, B= phos-peptide, C= dephos-peptide).

This antibody is predicted to react with bovine, canine, mouse, non-human primate and sheep based on 100% sequence homology.
It is specific for IFNAR1 protein phosphorylated at Ser535,539 in Western blots of human brain extracts.
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-& 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 539 in the IFNAR1 (Kumar et al., 2003).
