These neuroligin 3 (Nlgn3) targeted mutation mice carry an R704C mutation that reduces expression levels and impairs excitatory glutamatergic synaptic transmission.

Arginine 704 of the Nlgn3 (neuroligin 3) gene was mutated to cysteine (R704C) in this targeted mutation strain. Expression levels of this X-linked allele are reduced to approximately 70% of wild type levels in brain tissue. This mutation causes a selective impairment of excitatory glutamatergic synaptic transmission mediated by AMPA receptors in both cultured hippocampal neurons and acute hippocampal slices.
Arginine 704 (exon 8) was mutated to encode cysteine (R704C) and an FRT-flanked neomycin cassette (with a single, un-used loxP site) was placed in intron 7. The mutation was introduced to (129X1/SvJ x 129S1/Sv)F1- Kitl+-derived R1 embryonic stem (ES) cells. The neomycin selection cassette was excised from chimeric animals though crosses with an Actb beta actin promoter Flp recombinase mouse originally made on a B6SJLF2 background, and backcrossed to C57BL/6NCrl. This strain was maintained on a mixed 129 and C57BL/6 genetic background by the donating laboratory through alternated crosses of heterozygous females with wildtype 129S2/SvPasCrl and C57BL/6NCrl males to enhance breeding performance.

Molecular Note | Arginine 704 (exon 8) was mutated to encode cysteine (R704C) and an FRT-flanked neomycin cassette (with a single, un-used loxP site) was placed in intron 7. Flp-mediated recombination removed the neo cassette. |

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.
