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.

The common cytokine-binding domain is related to the Fibronectin type III domain.

Signal transduction chains
The signal transducing chains are often shared between different receptors within this receptor family.

 * IL-21 receptor
 * 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.
 * The gp130 receptor (Glycoprotein 130) (also known as gp130, IL6ST, IL6-beta or CD130) is shared between:
 * IL-6 receptor
 * IL-11 receptor
 * IL-12 receptor
