IFN-α Receptor Recognition Peptide 1  (Synonyms: IRRP1)

IFN-α Receptor Recognition Peptide 1 (IRRP1) is an amino acid synthetic peptide and also a regulator of IFN-α Receptor. IFN-α Receptor Recognition Peptide 1 binds to IFNAR2, enhances the binding capacity of IFN-α receptor, and slightly increases the IFN-α-induced growth inhibitory activity. IFN-α Receptor Recognition Peptide 1 inhibits IFN-α-induced STAT1 phosphorylation and STAT-DNA binding by blocking the activation of IFNAR by IFN-α. IFN-α Receptor Recognition Peptide 1 increases the occupancy of IFN-α on cell surface receptors, enhances the phosphorylation activation of ISGF3, and elevates IFN-α-induced antiviral activity. IFN-α Receptor Recognition Peptide 1 can be used in studies related to encephalomyocarditis virus infection^[1][2].

IFN-α Receptor Recognition Peptide 1 can enhance the IFN-α2 binding ability of Daudi cells^[2].
IFN-α Receptor Recognition Peptide 1 does not activate ISGF3 in Daudi cells alone, but enhances IFN-Con₁-induced ISGF3 activation when co-administered with 0.016 ng/mL IFN-Con₁^[2].
IFN-α Receptor Recognition Peptide 1 enhances IFN-Con₁-induced ISGF3 activation in MRC-5 cells when co-administered with 1.0 ng/mL IFN-Con₁^[2].
IFN-α Receptor Recognition Peptide 1 (1 μg/mL; 24 h) does not protect T98G cells from EMCV infection alone, but enhances the antiviral potency of sub-optimal doses of IFN-Con₁, increasing percent protection from EMCV CPE^[2].
IFN-α Receptor Recognition Peptide 1 (1 μg/mL; 96 h at 37°C) marginally enhances IFN-Con₁-induced growth inhibition in T98G cells, with the strongest effects at lower IFN-Con₁ doses^[2].
