Nrxn1 Knockout mouse models
Presynaptic adhesion in the mouse is organized by Nrxn1, ortholog of human NRXN1, which uses two promoters to produce long alpha-neurexin isoforms (six LNS domains interleaved with EGF repeats) and short beta-neurexins sharing a single transmembrane segment and a cytoplasmic tail that recruits CASK and Mint. Extensive alternative splicing at sites 1 through 6, particularly splice site 4, dictates trans-synaptic partner choice among neuroligins, LRRTMs, cerebellin-GluD complexes, and dystroglycan, thereby tuning calcium channel coupling and release probability. Human deletions and rare truncating variants segregate with autism, schizophrenia, and Pitt-Hopkins-like syndrome 2. Allele choice follows directly: conditional deletion of alpha-specific exons isolates presynaptic calcium coupling, splice-locked knockins interrogate isoform logic, and humanized cassettes support variant modeling. Because Nrxn2 and Nrxn3 substantially compensate, single-locus nulls are frequently silent, so plan triple conditional genetics with defined Cre drivers and match allele class to synaptic physiology endpoints.
Whole body loss of Nrxn1 gives the clearest readout when the question is whether the gene is required at all. Follow up tissue work can still move to a conditional allele if lethality or compensation appears.

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 Nrxn1 Knockout mouse models are available?
When Nrxn1 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 Nrxn1 knockout embryonic lethal in mice?
It depends on background and allele design. Some Nrxn1 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 Nrxn1 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 Nrxn1?
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.
