Target

Full Name
Interferon Alpha And Beta Receptor Subunit 2
Introduction
The protein encoded by this gene is a type I membrane protein that forms one of the two chains of a receptor for interferons alpha and beta. Binding and activation of the receptor stimulates Janus protein kinases, which in turn phosphorylate several proteins, including STAT1 and STAT2. Multiple transcript variants encoding at least two different isoforms have been found for this gene.
Entrez Gene ID
3455
UniProt ID
P48551
Alternative Names
Interferon Alpha And Beta Receptor Subunit 2
Function
Associates with IFNAR1 to form the plasma membrane receptor in the type I interferon signaling pathway (PubMed:26424569, PubMed:28165510, PubMed:32972995).

Directly involved in signal transduction through its association with the TYR kinase JAK1 (PubMed:8181059, PubMed:7665574, PubMed:7759950).

Involved in interferon-mediated STAT1, STAT2 and STAT3 activation (PubMed:26424569, PubMed:32972995).

Isoform 3:
Potent inhibitor of type I IFN receptor activity.

Involvement in disease
Immunodeficiency 45 (IMD45):
An autosomal recessive disorder characterized by increased susceptibility to viral infection due to impaired antiviral immunity, resulting in infection-associated encephalopathy. Affected individuals are at risk for developing fatal encephalitis after routine measles/mumps/rubella (MMR) vaccination.
Topology
Extracellular: 27-243
Helical: 244-264
Cytoplasmic: 265-515
PTM
Phosphorylated on tyrosine residues upon interferon binding. Phosphorylation at Tyr-337 or Tyr-512 are sufficient to mediate interferon dependent activation of STAT1, STAT2 and STAT3 leading to antiproliferative effects on many different cell types.
Glycosylated.
