To investigate the reason for the differential behavior of cells expressing K652E FGFR3, we assessed the phosphorylation levels of FGFR3 mutant proteins and downstream effectors in urothelial cells. All mutant forms of F
[Paragraph-level] PMCID: PMC2789045 Section: RESULTS PassageIndex: 15
Evidence Type(s): Functional, Oncogenic
Justification: Functional: The passage discusses how the K652E, S249C, and Y375C variants of FGFR3 alter phosphorylation levels and dimerization behavior, indicating changes in molecular function. Oncogenic: The variants are described in the context of their constitutive activation and behavior in urothelial cells, suggesting their role in tumor development or progression.
