  • Function

    Receptor for IL27. Requires IL6ST/gp130 to mediate signal transduction in response to IL27. This signaling system acts through STAT3 and STAT1. Involved in the regulation of Th1-type immune responses. Also appears to be involved in innate defense mechanisms.
  • Tissue specificity

    Highly expressed in lymphoid tissues such as spleen, lymph nodes and peripheral blood leukocytes. Weakly expressed in other tissues examined including heart, brain, fetal and adult lung, liver, skeletal muscle, kidney, pancreas, prostate, testis, ovary, small intestine, kidney and colon. In the lymphoid system, higher level expression in CD4+ T-cell subsets than in CD8+ T-cell subsets. Also weaker expression in CD19+ B-cells and monocytes.
  • Sequence similarities

    Belongs to the type I cytokine receptor family. Type 2 subfamily.
    Contains 3 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.

Customer reviews and Q&As


Thank you for contacting us. I am sorry to hear you are having problems with one of our products. Unfortunately, I am not available to send positive controls, but I can suggest using Human spleen tissue lysate with this antibody. We have in catalogue several lysates from Human Spleen Tissue if you are interested (see ab29699 and ab29689). https://www.abcam.com/Spleen-Human-Tissue-Lysate-adult-normal-tissue-ab29699.html https://www.abcam.com/Spleen-Human-Membrane-Lysate-adult-normal-tissue-ab29689.html However, I would be very happy to help you solve the problems experienced, and if no suggestions can be made to the protocol, and the antibody was purchased within the last 6 months, it is covered by our Abpromise guarantee, and therefore I can offer you a free of charge replacement or a credit note for it. I would appreciate if you could send me further details about the sample preparation such as the lysis buffer, the incubation process, the blocking conditions, etc... I send you a questionnaire attached to this email, which only takes about 5 minutes to be filled, and it will be very helpful to us to better understand why the antibody did not perform as stated in the datasheet. I would also appreciate if you could send us an image of the membrane, to better understand the problem. I look forward to receiving your reply. Please do not hesitate to contact us if you need any more advice or information.
