Nrxn2 Knockout mouse models
Although often treated as the minor paralog, Nrxn2 encodes the mouse ortholog of human NRXN2, an alpha and beta neurexin pair whose extracellular LNS and EGF modules bind neuroligins, LRRTMs, and cerebellin adaptors to align presynaptic release machinery with postsynaptic receptor fields. Its cytoplasmic tail terminates in a PDZ-binding motif engaging CASK, linking the adhesion complex to voltage-gated calcium channels and the active zone. Truncating NRXN2 variants have been reported in autism and schizophrenia pedigrees, and alpha-Nrxn2 null mice show altered social behavior and anxiety with region-specific transmission deficits. Design decisions therefore split between conditional alpha-specific exon removal, beta-selective ablation, splice site 4 fixed knockins, and humanization for variant testing. Given strong functional overlap with Nrxn1 and Nrxn3, compound conditional alleles are usually required to unmask phenotypes, and pairing them with an interneuron or projection-specific Cre determines whether readouts are electrophysiological, behavioral, or ultrastructural.
Nrxn2 null animals are straightforward to genotype and phenotype when survival is acceptable. They remain a standard background for pharmacology, biomarker, and rescue studies.
What Nrxn2 Knockout mouse models are available?
ingenious targeting laboratory offers 3 distinct Nrxn2 knockout catalog mouse models. Researchers can order pre-developed catalog lines or request a custom mouse model, including humanized, knockin, and transgenic variations with verified germline transmission.
Why this approach
A conventional knockout answers whether the gene is required broadly. When your target tissue is the organ of interest, a global null can still be informative if viability is acceptable and you want the simplest genotype. If the null is harsh, a floxed allele with a regional Cre is the safer long term platform.

FAQ
What Nrxn2 Knockout mouse models are available?
When Nrxn2 Knockout lines are in catalog, we ship from inventory. If your configuration is not listed, we design the allele to order. Common paths include conditional knockout, constitutive knockout, humanized, knockin, and transgenic options, with documented germline transmission and United States QC.
Is Nrxn2 knockout embryonic lethal in mice?
It depends on background and allele design. Some Nrxn2 germline knockouts are viable. Others need conditional alleles or mixed backgrounds. We review publications and our own experience, then recommend floxed versus null before you commit.
Which Cre driver is best for experiments?
Driver choice depends on onset timing, recombination efficiency, and known leak. We map your organ and cell type to a short list of proven Cre lines, then talk through reporter crosses and controls. We favor drivers with strong community validation for your tissue.
Do you ship live Nrxn2 animals?
When catalog lines are live, we ship with health certificates and QC documentation. If your exact combo is not listed, we quote a generation project with cryo or live dispatch depending on cohort timing and geography.
How do I request a quote for Nrxn2?
Use the catalog inquire buttons or the request quote form. Include your allele goal, Cre plan if any, strain background, and cohort size. A PhD led team responds with pricing, milestones, and the fastest path to experimental animals.
