  • FunctionAssociates with IFNAR1 to form the type I interferon receptor. Receptor for interferons alpha and beta. Involved in IFN-mediated STAT1, STAT2 and STAT3 activation. Isoform 1 and isoform 2 are directly involved in signal transduction due to their association with the TYR kinase, JAK1. Isoform 3 is a potent inhibitor of type I IFN receptor activity.
  • Tissue specificityIsoform 3 is detected in the urine (at protein level). Expressed in blood cells. Expressed in lymphoblastoid and fibrosarcoma cell lines.
  • Sequence similaritiesBelongs to the type II cytokine receptor family.
  • Post-translational
    modifications
    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.
  • Cellular localizationSecreted and Membrane.
  • Information by UniProt

Active human IFNAR2 full length protein images

  • Densitometry of protein isoforms visualised by 2-DE. The triangle indicates the theoretical MW and pI of the protein.
  • 1D SDS-PAGE of ab83680 before and after treatment with glycosidases to remove oligosaccharides.
    Lane 1 MW markers; Lane 2 ab83680; Lane 3 ab83680 treated with PNGase F to remove potential N-linked glycans; Lane 4 ab83680 treated with a glycosidase cocktail to remove potential N- and O-linked glycans. Approximately 5 µg of protein was loaded per lane.

    Drop in MW after treatment with PNGase F indicates presence of N-linked glycans. A further drop in MW after treatment with the glycosidase cocktail indicates the presence of O-linked glycans. Additional bands in lane 3 and lane 4 are glycosidase enzymes.

  • A sample of ab83680 without carrier protein was reduced and alkylated and focused on a 3-10 IPG strip then run on a 4-20% Tris-HCl 2D gel. Approximately 40 µg of protein was load; Gel was stained using Deep Purple™.
