These Neto2, neuropilin (NRP) and tolloid (TLL)-like 2, targeted mutation mice exhibit impaired neuronal potassium chloride (KCC2) co-transporter function and have applications in studies of ionotropic glutamate receptors and synaptic plasticity.

Targeted (Null/Knockout) | Neto2 | neuropilin (NRP) and tolloid (TLL)-like 2 |
Neuropilin (NRP) and tolloid (TLL)-like 2 contains two extracellular CUB domains and a low-density lipoprotein class A (LDLa) domain and functions as an auxillary subunit of neuronal kainate-sensitive glutamate receptors. These mice carry a targeted mutation of the Neto2 (Neuropilin (NRP) and tolloid (TLL)-like 2 contains 2) gene, in which exons 3 through 6 are replaced by a NEO cassette.
Homozygotes are viable and fertile. No gene product (protein) is detected by immunoblot analysis of brain lysates from homozygotes. Mutant mice exhibit impaired neuronal potassium chloride (KCC2) co-transporter activity and reduced KCC2 protein levels.
During backcrossing, the Y chromosome may not have been fixed to the C57BL/6N genetic background.
Dr. Roderick R. McInnes, while at University of Toronto, designed a targeting vector that contains a
NEO cassette to disrupt exons 3 through 6 of the targeted gene. The construct was electroporated into 129 derived R1 embryonic stem (ES) cells. Correctly targeted ES cells were injected into C57BL/6J blastocysts. The resulting male chimeric animals were crossed to C57BL/6J mice, and then backcrossed to C57BL/6NCrl for more than 10 generations. During backcrossing, the Y chromosome may not have been fixed to the C57BL/6NCrl genetic background.
Upon arrival at The Jackson Laboratory, the mice were crossed to C57BL/6NJ
(Stock No. 005304) at least once to establish the colony.

Chromosome | 8 |
Molecular Note | Exons 3 - 6 were replaced with a neo cassette via homologous recombination. Immunoblot analysis of brain lysates from homozygous mice confirms the absence of protein expression. |
When maintaining a live colony, these mice can be bred as homozygotes.

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.
