Type I cytokine receptor

Type I cytokine receptors are transmembrane receptors expressed on the surface of cells that recognize and respond to cytokines with four α-helical strands. These receptors are also known under the name hemopoietin receptors, and share a common amino acid motif (WSXWS) in the extracellular portion adjacent to the cell membrane. Members of the type I cytokine receptor family comprise different chains, some of which are involved in ligand/cytokine interaction and others that are involved in signal transduction.

Signal transduction chains

The signal transducing chains are often shared between different receptors within this receptor family.^[1]

• The IL-2 receptor common gamma chain (also known as CD132) is shared between:
  • IL-2 receptor
  • IL-4 receptor
  • IL-7 receptor
  • IL-9 receptor
  • IL-13 receptor
  • IL-15 receptor^[2]

• The common beta chain (CD131 or CDw131) is shared between the following type I cytokine receptors:
  • GM-CSF receptor
  • IL-3 receptor
  • IL-5 receptor.^[3]

• The gp230 receptor common gamma chain (also known as gp130, IL6ST, IL6-beta or CD130) is shared between:
  • IL-6 receptor
  • IL-11 receptor
  • Leukamia inhibitory factor receptor
  • Oncostatin M receptor
