Journal ArticleDOI
Cellular signaling by fibroblast growth factor receptors.
TL;DR: The 22 members of the fibroblast growth factor (FGF) family of growth factors mediate their cellular responses by binding to and activating the different isoforms encoded by the four receptor tyrosine kinases (RTKs) designated FGFR1, FGFR2,FGFR3 and FGFR4.
Journal ArticleDOI
Amplification, enhanced expression and possible rearrangement of EGF receptor gene in primary human brain tumours of glial origin
Towia A. Libermann,Harris R. Nusbaum,Nissim Razon,Richard Kris,Irit Lax,Hermona Soreq,Nigel Whittle,Michael D. Waterfield,Axel Ullrich,Joseph Schlessinger +9 more
TL;DR: 4 of 10 primary brain tumours of glial origin which express levels of EGF receptors that are higher than normal also have amplified EGF receptor genes, suggesting that such altered expression and amplification is a particular feature of certain human tumours.
Journal ArticleDOI
A lipid-anchored Grb2-binding protein that links FGF-receptor activation to the Ras/MAPK signaling pathway
H. Kouhara,Y. R. Hadari,T Spivak-Kroizman,J Schilling,Dafna Bar-Sagi,Irit Lax,Joseph Schlessinger +6 more
TL;DR: It is found that FRS2 is myristylated and that this modification is essential for membrane localization, tyrosine phosphorylation, Grb2/Sos recruitment, and MAPK activation.
Journal ArticleDOI
Heparin-induced oligomerization of FGF molecules is responsible for FGF receptor dimerization, activation, and cell proliferation.
T Spivak-Kroizman,Mark A. Lemmon,Ivan Dikic,John E. Ladbury,Dalia Pinchasi,Jiaoti Huang,Michael Jaye,Gregg Crumley,Joseph Schlessinger,Irit Lax +9 more
TL;DR: It is proposed that heparin causes oligomerization of aFGF such that its binding to FGFR results in dimerization and activation, which represents a novel mechanism for transmembrane signaling and may account for the action of many heParin-bound growth factors.
Journal ArticleDOI
Regulation of growth factor activation by proteoglycans: What is the role of the low affinity receptors?
TL;DR: The existence of nonsignaling as well as signaling receptors for the same ligand is a feature common for many growth factors and the need for a different model to understand the role of the low affinity receptors is demonstrated.
