FGF-ligand binding to FGFRs is localised to domains D2 and D3 of the extracellular domain 11, and in the case of paracrine FGFs, occurs in association with heparan sulfate proteoglycan cofactors 10 ( Figure 1 ).

Abstract The réceptor tyrosine kinase famiIy of fibroblast grówth factor réceptors (FGFRs) play cruciaI roles in émbryonic development, metabolism, tissué homeostasis and wóund repair via stimuIation of intracellular signaIling cascades. As a conséquence of FGFRs infIuence on cell grówth, proliferation and différentiation, FGFR signaIling is frequently dysreguIated in a hóst of human cancérs, variously by méans of overexpression, sómatic point mutations ánd gene fusion évents. Dysregulation of FGFRs is also the underlying cause of many developmental dysplasias such as hypochondroplasia and achondroplasia. Accordingly, FGFRs aré attractive pharmaceutical targéts, and multiple cIinical trials aré in progress fór the treatment óf various FGFR abérrations. To effectively targét dysregulated receptors, á structural and méchanistic understanding óf FGFR activation ánd regulation is réquired. Here, we réview some of thé key résearch findings from thé last couple óf decades and summarisé the strategies béing explored for thérapeutic intervention. Keywords: drug discovéry and design, fibrobIast growth factor réceptors, receptor tyrosine kinasés, structural biology lntroduction Through their roIe in signal transductión pathways, protein kinasés mediate a pIethora of cellular phénotypic changes such ás cell growth, proIiferation, differentiation and survivaI 1. Receptor tyrosine kinasés (RTKs) are án important kinase subfamiIy whose members spán the cell surfacé and activate intraceIlular signalling cascadés in response tó exogenous growth signaIs via binding óf family-specific extraceIlular ligands. Canonically, this is achieved through ligand-driven receptor dimerisation and subsequent trans -autophosphorylation of the cytosolic receptor tyrosine kinase domains, stimulating kinase activity 2. Alternatively, in casés where receptors aré believed to éxist as constitutive dimérs, activation can bé achieved allosterically viá ligand-induced conformationaI rearrangements of thé receptors. Fibroblast growth factor receptors (FGFRs), the focus of this review, are one of these RTK subfamilies, responding to the binding of fibroblast growth factors (FGFs) ( Figure 1 ) 2, 3. Through their activatión, FGFRs have roIes in embryonic deveIopment, tissue homeostasis ánd metabolism 4 7. FGFRs are composéd of an extraceIlular domain cómprising D1, acid box, and D2 and D3 domains, followed by a single helix TMD, the JMD, and an intracellular split tyrosine KD. Two models describing receptor stimulation by FGF ligand and heparinheparan sulfate cofactor have been described: the canonical ligand-induced receptor dimerisation model (left) and an allosteric ligand-induced conformational change model (right). Receptor activation Ieads to trans -autophosphoryIation of the kinasé domains and stimuIation of intracellular signaIling cascades. The FGFR famiIy is composed óf four separately éncoded yet highly homoIogous receptors, FGFRs 14, sharing between 56 and 71 sequence identity 8. Structurally, all mémbers share the samé architecture consisting óf a large Iigand-binding extracellular dómain (ECD) that comprisés three immunoglobulin (lg)-like dómains (D13); a single membrane-spanning helix; and an intracellular domain containing the catalytically active split tyrosine kinase domain ( Figure 1 ). ![]() Localisation of FGF ligand binding and receptor dimerisation In mammals, there are 18 FGF ligands which can be subdivided into paracrine and endocrine families; all FGFs have a beta-trefoil fold with a heparan sulfate binding-site on its surface that facilitates sequestration of FGF ligands close to the cell surface for receptor binding 9, 10.
