Gria3 Knockout mouse models
Gria3 is X-linked in both species and, as the ortholog of human GRIA3, encodes GluA3, an AMPA receptor subunit with a short cytoplasmic tail that supports constitutive, activity-independent receptor cycling through PICK1 and GRIP interactions, in contrast with the regulated insertion driven by GluA1. GluA3-containing receptors are abundant in hippocampus, cortex, and auditory brainstem, and their fast kinetics depend on flip and flop splicing plus TARP association. Human GRIA3 missense variants produce X-linked intellectual disability with both loss-of-function and gain-of-function gating changes, including slowed deactivation and shifted agonist potency, which is why patient-specific knockin alleles are usually more informative than deletion. Constitutive nulls are viable with subtle synaptic phenotypes, so conditional alleles are reserved for cell-type attribution rather than for bypassing lethality. Because Gria1 and Gria2 readily substitute in heteromers, score subunit-resolved currents and rectification, and use humanized alleles when testing modulators with species-divergent binding sites.
Gria3 null animals are straightforward to genotype and phenotype when survival is acceptable. They remain a standard background for pharmacology, biomarker, and rescue studies.
What Gria3 Knockout mouse models are available?
ingenious targeting laboratory offers 2 distinct Gria3 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 Gria3 Knockout mouse models are available?
When Gria3 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 Gria3 knockout embryonic lethal in mice?
It depends on background and allele design. Some Gria3 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 Gria3 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 Gria3?
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.
