Strain developmentDeveloped by Dr. Nobuhiko Kojima, National Institute for Physiological Sciences, Japan at 1994. The FynB fragment mutated from TAT to TTT at codon 531 by site-directed mutagenesis under the control of the CaMKII alpha promoter was injected into the pronuclei of B6CBF1 fertilized egges. The transgenic mice were backcross to C57BL/6J mice for 26 generations.Generation:N23+N3
Strain descriptionB6.Cg-Tg(Camk2a-Fyn-531)1Nko/Rbrc. Transgenic mice overexpressing activated form of Fyn under the control of the calcium/calmodulin-dependent protein kinase II alpha promoter. The transgenic mutant Fyn is expressed at high levels in neurons of the forebrain. The transgenic mice exhibit seizure activity by stimulus of drug and light, accelerated kindling, and spontaneous death after weaning. The survival rate of these mice correlates inversely with the expression level of mutant Fyn. This strain is useful for elucidation of the role of Fyn tyrosine kinase in synaptic plasticity.
Colony maintenanceBackcross to C57BL/6 (Hemizygote x C57BL/6JJcl)Reproductive performance is good.
