Preparation and Storage

  • Stability and Storage

    Shipped at 4°C. Store at 4°C prior to reconstitution. Store at -80°C. Avoid freeze / thaw cycle. Reconstitute for long term storage.

    pH: 7.40
    Constituents: 95% PBS, 5% Trehalose

    This product is an active protein and may elicit a biological response in vivo, handle with caution.

  • Reconstitution
    It is recommended to reconstitute the lyophilized protein in sterile deionized water to a final concentration of 1mg/ml. Solubilize for 30 to 60 minutes at room temperature with occasional gentle mixing. Carrier protein (0.1% HSA or BSA) is strongly recommended for further dilution and long term storage.

  • Function

    This is a receptor for interleukin-21.
  • Tissue specificity

    Selectively expressed in lymphoid tissues. Most highly expressed in thymus and spleen.
  • Sequence similarities

    Belongs to the type I cytokine receptor family. Type 4 subfamily.
    Contains 2 fibronectin type-III domains.
  • Domain

    The WSXWS motif appears to be necessary for proper protein folding and thereby efficient intracellular transport and cell-surface receptor binding.
    The box 1 motif is required for JAK interaction and/or activation.
  • Post-translational
    modifications

    C-mannosylated at Trp-214 in the WSXWS motif, the sugar chain makes extensive hydrogen bonds with Asn-73 sugar, and bridges the two fibronectin domains transforming the V-shaped receptor into an A-frame.
  • Cellular localization

    Membrane.
  • Information by UniProt
