Bioactivity Comments
As this drug is an interferon α analogue it will interact with the interferon-α/β receptor (IFNAR) as would the endogenous ligand. We have tagged the interferon α/β receptor 1 (IFNAR1- ligand binding subunit) and IFNAR (heterodimeric receptor) as primary drug targets, despite a lack of available affinity data.
