Phenotypic expression of the fibroblast growth factor receptor 3 (FGFR3) mutation P250R in a large craniosynostosis family.
1997
The craniosynostosis syndromes are a heterogeneous group of sporadic, autosomal dominant disorders with significant clinical overlap. Recently, we described a large family with autosomal dominant craniosynostosis suggestive of Saethre-Chotzen syndrome, in which linkage to the Saethre-Chotzen syndrome loci on 7p had been excluded. We now report the presence of a mutation in the fibroblast growth factor receptor 3 (FGFR3) in this family. The mutation, P250R, had been previously reported in 10 patients with non-syndromic craniosynostosis. Variable expression of this mutation is evident especially in two additional members of this family, one of whom is severely affected with pancraniosynostosi…
Expression and glycosylation studies of human FGF receptor 4
2001
Fibroblast growth factor receptor subtype 4 (FGFR4) has been shown to have special activation properties and just one splicing form, unlike the other FGFRs. FGFR4 overexpression is correlated with breast cancer and therefore FGFR4 is a target for drug design. Our aim is to overexpress high amounts of homogeneous FGFR4 extracellular domain (FGFR4ed) for structural studies. We show that baculovirus-insect cell-expressed FGFR4ed is glycosylated on three (N88, N234, and N266) of the six possible N-glycosylation sites but is not O-glycosylated. The deglycosylated triple mutant was expressed and had binding properties similar to those of glycosylated FGFR4ed, but was still heterogeneous. Large am…
