[https://www.uniprot.org/uniprot/FGFR1_HUMAN FGFR1_HUMAN] Tyrosine-protein kinase that acts as cell-surface receptor for fibroblast growth factors and plays an essential role in the regulation of embryonic development, cell proliferation, differentiation and migration. Required for normal mesoderm patterning and correct axial organization during embryonic development, normal skeletogenesis and normal development of the gonadotropin-releasing hormone (GnRH) neuronal system. Phosphorylates PLCG1, FRS2, GAB1 and SHB. Ligand binding leads to the activation of several signaling cascades. Activation of PLCG1 leads to the production of the cellular signaling molecules diacylglycerol and inositol 1,4,5-trisphosphate. Phosphorylation of FRS2 triggers recruitment of GRB2, GAB1, PIK3R1 and SOS1, and mediates activation of RAS, MAPK1/ERK2, MAPK3/ERK1 and the MAP kinase signaling pathway, as well as of the AKT1 signaling pathway. Promotes phosphorylation of SHC1, STAT1 and PTPN11/SHP2. In the nucleus, enhances RPS6KA1 and CREB1 activity and contributes to the regulation of transcription. FGFR1 signaling is down-regulated by IL17RD/SEF, and by FGFR1 ubiquitination, internalization and degradation.<ref>PMID:20139426</ref> <ref>PMID:1379697</ref> <ref>PMID:1379698</ref> <ref>PMID:8622701</ref> <ref>PMID:8663044</ref> <ref>PMID:11353842</ref> <ref>PMID:12181353</ref> <ref>PMID:15117958</ref> <ref>PMID:16597617</ref> <ref>PMID:17623664</ref> <ref>PMID:17311277</ref> <ref>PMID:18480409</ref> <ref>PMID:19261810</ref> <ref>PMID:19224897</ref> <ref>PMID:21765395</ref> <ref>PMID:10830168</ref> <ref>PMID:19665973</ref> <ref>PMID:20133753</ref>

The binding of a ligand to its target protein is often accompanied by conformational changes of both the protein and the ligand. This is of particular interest, since structural rearrangements of the macromolecular target and the ligand influence the free energy change upon complex formation. In this study, we use X-ray crystallography, isothermal titration calorimetry, and surface-plasmon resonance biosensor analysis to investigate the binding of pyrazolylaminopyrimidine inhibitors to FGFR1 tyrosine kinase, an important anticancer target. Our results highlight that structurally close analogs of this inhibitor series interact with FGFR1 with different binding modes, which are a consequence of conformational changes in both the protein and the ligand as well as the bound water network. Together with the collected kinetic and thermodynamic data, we use the protein-ligand crystal structure information to rationalize the observed inhibitory potencies on a molecular level.
