Interferon alfa-n1

Targets (2)Enzymes (1)

Identification

Name
Interferon alfa-n1
Accession Number
DB00011
Description

Interferon alfa-n1 consists of purified, natural (n is for natural) alpha interferon subtypes, at least two of which are glycosylated. This differs from recombinant alpha interferons, which are individual non-glycosylated proteins produced from individual alpha interferon genes.

Pharmacodynamics

Upregulates the expression of MHC I proteins, allowing for increased presentation of peptides derived from viral antigens. This enhances the activation of CD8+ T cells that are the precursors for cytotoxic T lymphocytes (CTLs) and makes the macrophage a better target for CTL-mediated killing. Interferon alpha also induce the synthesis of several key antiviral mediators, including 2'-5' oligoadenylate synthetase (2'-5' A synthetase) and protein kinase R.

Mechanism of action

Interferon alpha binds to type I interferon receptors (IFNAR1 and IFNAR2c) which, upon dimerization, activate two Jak (Janus kinase) tyrosine kinases (Jak1 and Tyk2). These transphosphorylate themselves and phosphorylate the receptors. The phosphorylated INFAR receptors then bind to Stat1 and Stat2 (signal transducers and activators of transcription)which dimerize and activate multiple (~100) immunomodulatory and antiviral proteins. Interferon alpha binds less stably to type I interferon receptors than interferon beta.
