A disorder characterized by absent or incomplete sexual maturation by the age of 18 years, in conjunction with low levels of circulating gonadotropins and testosterone and no other abnormalities of the hypothalamic-pituitary axis. In some cases, it is associated with non-reproductive phenotypes, such as anosmia, cleft palate, and sensorineural hearing loss. Anosmia or hyposmia is related to the absence or hypoplasia of the olfactory bulbs and tracts. Hypogonadism is due to deficiency in gonadotropin-releasing hormone and probably results from a failure of embryonic migration of gonadotropin-releasing hormone-synthesizing neurons. In the presence of anosmia, idiopathic hypogonadotropic hypogonadism is referred to as Kallmann syndrome, whereas in the presence of a normal sense of smell, it has been termed normosmic idiopathic hypogonadotropic hypogonadism (nIHH).<ref>PMID:20139426</ref> <ref>PMID:12627230</ref> <ref>PMID:15001591</ref> <ref>PMID:15605412</ref> <ref>PMID:15845591</ref> <ref>PMID:16882753</ref> <ref>PMID:16764984</ref> <ref>PMID:16757108</ref> <ref>PMID:16606836</ref> <ref>PMID:17154279</ref> Defects in FGFR1 are the cause of osteoglophonic dysplasia (OGD) [MIM:[https://omim.org/entry/166250 166250]]; also known as osteoglophonic dwarfism.

| - | [[ | + | [[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> |

| + | RATIONALE: The protein kinase FGFR1 regulates cellular processes in human development. As over-activity of FGFR1 is implicated with cancer, effective inhibitors are in demand. Type I inhibitors, which bind to the active form of FGFR1, are less effective than type II inhibitors, which bind to the inactive form. Screening to distinguish between type I and type II inhibitors is required. METHODS: X-Ray crystallography was used to indicate whether a range of potential inhibitors bind to the active or inactive FGFR1 kinase conformation. The binding affinity of each ligand to FGFR1 was measured using biochemical methods. ESI-IMS-MS in conjunction with collision-induced protein unfolding generated a conformational profile of each FGFR1-ligand complex. The results indicate that the protein's conformational profile depends on whether the inhibitor is type I or type II. RESULTS: X-Ray crystallography confirmed which of the kinase inhibitors bind to the active or inactive form of FGFR1 kinase. Collision-induced unfolding combined with ESI-IMS-MS showed distinct differences in the FGFR1 folding landscape for type I and type II inhibitors. Biochemical studies indicated a similar range of FGFR1 affinities for both types of inhibitors, thus providing confidence that the conformational variations detected using ESI-IMS-MS can be interpretated unequivocally and that this is an effective screening method. CONCLUSION: A robust ESI-IMS-MS method has been implemented to distinguish between the binding mode of type I and type II inhibitors by monitoring the conformational unfolding profile of FGFR1. This rapid method requires low sample concentrations and could be used as a high-throughput screening technique for the characterisation of novel kinase inhibitors. | ||
