Strain Information

BRC No.RBRC01840
TypeTargeted MutationCartagena
SpeciesMus musculus
Strain nameB6.Cg-Grin2d<tm1Mim>/MimRbrc
Former Common nameGluRε4 KO mouse
H-2 Haplotype
ES Cell lineTT2 [(C57BL/6NCrlj x CBA/JNCrlj)F1]
Background strainC57BL/6
Strain developmentDeveloped by Kazutaka Ikeda and Masami Mishina, Brain Research Institute, Niigata University in 1995. A pgk-neo was transfered into TT2 ES cells to replace the exon encoding the M4 putative transmembrane segment of Grin2d gene. The mutant mice were backcrossed to C57BL/6N over 10 times.
Strain descriptionGluR epsilon4 (Grin2d, glutamate receptor, ionotropic, NMDA2D (epsilon 4)) knockout mice. The Grin2d gene is one of the glutamate receptor channel subunit families forming NMDA receptor channel. The Grin2d homozygous mutant mice show a reduced spontaneous activity, but no significant difference in motor activity and anxiety tests when compared with normal mice. Reproductive performance and growth of them is normal.
Colony maintenanceHeterozygote x Wild-type [C57BL/6NJcl]. Homozygous mutant mice are viable and fertile.
