bFGF-induced-c-fos expression was reduced by inhibition of FGFR-1 , but not by L-type Ca2+ channel inhibition , demonstrating that stimulation of FGFR-1 results in a Ca2+ channel independent change of gene expression
Kan et al., J Biol Chem 1996
:
In contrast, the high affinity interaction ( apparent Kd = 10 nM ) of heparin with FGFR requires Ca2+ or Mg2+ at physiological concentrations
