Application Abreviews Notes
Flow Cyt Use at an assay dependent concentration. PubMed: 24388011ab171870-Rabbit polyclonal IgG, is suitable for use as an isotype control with this antibody.
WB Use a concentration of 3 - 5 µg/ml. Detects a band of approximately 29 kDa (predicted molecular weight: 29 kDa).


  • FunctionReceptor for interleukin-33 (IL-33), its stimulation recruits MYD88, IRAK1, IRAK4, and TRAF6, followed by phosphorylation of MAPK3/ERK1 and/or MAPK1/ERK2, MAPK14, and MAPK8. Possibly involved in helper T-cell function.
  • Tissue specificityHighly expressed in kidney, lung, placenta, stomach, skeletal muscle, colon and small intestine. Isoform A is prevalently expressed in the lung, testis, placenta, stomach and colon. Isoform B is more abundant in the brain, kidney and the liver. Isoform C is not detected in brain, heart, liver, kidney and skeletal muscle.
  • Sequence similaritiesBelongs to the interleukin-1 receptor family.
    Contains 3 Ig-like C2-type (immunoglobulin-like) domains.
    Contains 1 TIR domain.
