Long hematopoietin receptor, gp130 family signature


A number of receptors for lymphokines, hematopoietic growth factors and growth hormone-related molecules have been found to share a common binding domain. These receptors are designated as hematopoietin receptors [1,2] and the corresponding ligands as hematopoietins. Further, hematopoietins have been subdivided into two major structural groups: Large/long and small/short hematopoietins.

One subset of individual receptor chains that are part of receptor complexes for large hematopoietins contain common structural elements in their extracellular parts: an immunoglobin-like domain, an hematopoietin-receptor domain, and 3 fibronectin type-III domains (2 in the leptin receptor). This subgroup was designated as "gp130 family of receptors" [3] and contains the following chains:

  • Leptin receptor (LPTR).
  • Granulocyte colony stimulating factor receptor (GCSFR).
  • Interleukin-6/-11/LIF/OSM/CNTF common β chain (GP130).
  • Leukemia inhibiting factor receptor (LIFR).
  • Oncostatin-M receptor β chain (OSMR).
  • Interleukin-12 receptor β-1 chain (IL12RB1).
  • Interleukin-12 receptor β-2 chain (IL12RB2).

A schematic representation of the structure of these receptors is shown below:

 |Ig-like| C C  C  C Extracellular |    FnIII (x3)   XXXXXXX   Cytoplasmic   |
           | |  |  |                              Transmembrane
           +-+  +--+

These receptor chains homodimerize (GCSFR, GP130, LPTR) or heterodimerize (GP130 with LIFR or OSMR, IL12RB1 with IL12RB2) upon binding of the cognate cytokine: G-CSF, LIF, OSM, LPT, or the cytokine/α chain complex: IL-6/IL6RA, IL-11/IL11RA, CNTF/CNTFRA, IL-12 (p35/p40) [4,5].

We have used one pattern to detect this family. The motif covers the c-terminal end of the first fibronectin III domain and the n-terminal part of the second fibronectin III domain.
