Background & Aims: Fibroblast growth factor receptor type II (FGFR2b) is the essential factor of cellular signal transduction that regulates important biological processes including cell proliferation and differentiation. The inpairment in the signaling of these receptors is associated with several human pathology. Various factors including toxic metals can change the signaling pathways. This study was aimed to investigate the effects of Nickel as the toxic metal on the structure of FGFR2b.

Materials & Methods: In this study, by using plasmid pLEICS-01, BL21 bacterial, induction of IPTG, electrophoresis and column containing Ni2+ -NTA the recombinant FGFR2b was expressed and purified. The effects of Ni concentrations under 100 mM on the structure of the protein kinase domain by Spectrofluorometer and Circular dichroism (CD) was studied.

Resultas: The nickel concentrations (under 100 mM) do not have a significant impact on the regular secondary structure of the protein. But they show a minor change in natural emission of tryptophan in the tertiary structure.

Conclusion: The main structure and stability kinase domain of the fibroblast growth factor receptor type II does not change by nickel.
