Receptor tyrosine kinase class III signature





Description

A number of growth factors stimulate mitogenesis by interacting with a family of cell surface receptors which possess an intrinsic, ligand-sensitive, protein tyrosine kinase activity [1]. These receptor tyrosine kinases (RTK) all share the same topology: an extracellular ligand-binding domain, a single transmembrane region and a cytoplasmic kinase domain. However they can be classified into at least five groups. The class III RTK's are characterized by the presence of five to seven immunoglobulin-like domains [2] in their extracellular section. Their kinase domain differs from that of other RTK's by the insertion of a stretch of 70 to 100 hydrophilic residues in the middle of this domain. The receptors currently known to belong to class III are:

  • Platelet-derived growth factor receptor (PDGF-R). PDGF-R exists as a homo- or heterodimer of two related chains: α and β [3].
  • Macrophage colony stimulating factor receptor (CSF-1-R) (also known as the fms oncogene).
  • Stem cell factor (mast cell growth factor) receptor (also known as the kit oncogene).
  • Vascular endothelial growth factor (VEGF) receptors Flt-1 and Flk-1/KDR [4].
  • Fl cytokine receptor Flk-2/Flt-3 [5].
  • The putative receptor Flt-4 [6].

We developed a signature pattern for this class of RTK's which is based on a conserved region in the kinase domain.
