This mutation of Gria2 (glutamate receptor, ionotropic, AMPA2 (alpha 2); GluR2) incorporates a deletion of the last seven transcribed amino acids, eliminating the C-terminal type II PDZ ligand and disrupting the interaction with PICK1 and GRIP1/2. This strain may be useful for further characterization of the targeted gene's synaptic function.

This mutation of Gria2 (glutamate receptor, ionotropic, AMPA2 (alpha 2); GluR2) incorporates a deletion of the last seven transcribed amino acids, eliminating the C-terminal type II PDZ ligand and disrupting the interaction with PICK1 (protein interacting with C kinase 1) and GRIP1/2 (glutamate receptor interacting proteins 1 and 2). Normal GRIA2 protein expression is replaced by the mutant form in the brain. This strain may be useful for further characterization of the targeted gene's synaptic function.
A loxP-flanked neomycin cassette was inserted into the intron right before the exon encoding the C-terminus region of the targeted gene. An artificial stop codon plus an additional AatII restriction enzyme site was introduced by PCR mutagenesis so as to eliminate the last seven amino acids from the translated protein. The mutation was created using (129X1/SvJ x 129S1/Sv)F1- Kitl+-derived R1 embryonic stem (ES) cells. Heterozygous mice were bred to CMV-cre transgenic mice to delete the neomycin resistance cassette. The strain was backcrossed to C57BL/6 for 12 generations by the donating laboratory.

Strain of Origin | (129X1/SvJ x 129S1/Sv)F1-Kitl+ |
Chromosome | 3 |
Molecular Note | An artificial stop codon was inserted upstream of the exon encoding transmembrane 4 and the C terminus region. A floxed neo included in the construct was deleted via cre-mediated recombination. Western blot failed to detect protein using the antibody designed to recognize the last 7 amino acids of the C terminus. |

The Jackson Laboratory has rigorous genetic quality control and mutant gene genotyping programs to ensure the genetic background of JAX® Mice strains as well as the genotypes of strains with identified molecular mutations. JAX® Mice strains are only made available to researchers after meeting our standards. However, the phenotype of each strain may not be fully characterized and/or captured in the strain data sheets. Therefore, we cannot guarantee a strain's phenotype will meet all expectations. To ensure that JAX® Mice will meet the needs of individual research projects or when requesting a strain that is new to your research, we suggest ordering and performing tests on a small number of mice to determine suitability for your particular project. We do not guarantee breeding performance and therefore suggest that investigators order more than one breeding pair to avoid delays in their research.
