What Kcnj3 Knockout mouse models are available?

When Kcnj3 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 Kcnj3 knockout embryonic lethal in mice?

It depends on background and allele design. Some Kcnj3 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 Kcnj3 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 Kcnj3?

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.

Why model Kcnj3

Encoding GIRK1 (Kir3.1), Kcnj3 is the mouse ortholog of human KCNJ3 and supplies a subunit that cannot form functional homotetramers and instead obligately partners with GIRK2 or GIRK4 to build G protein-gated inwardly rectifying potassium channels. These channels are opened directly by Gbeta gamma dimers released from Gi and Go-coupled receptors, including GABA-B, M2 muscarinic, opioid, adenosine A1, and D2 receptors, with PIP2 and intracellular sodium acting as required cofactors and RGS proteins setting deactivation kinetics. GIRK1-containing channels mediate slow inhibitory postsynaptic currents in hippocampus and cortex and the atrial IKACh that slows heart rate. Because the subunit is obligatorily heteromeric, deletion removes surface channels rather than reducing a parallel conductance, and conditional alleles with forebrain or interneuron Cre drivers cleanly separate central from cardiac phenotypes. Kcnj6 and Kcnj5 products remain partially functional without GIRK1, so quantify residual Gbeta gamma-activated current, and use humanized alleles for GIRK-selective modulator campaigns.

What Kcnj3 mouse models are available?

ingenious targeting laboratory offers 1 distinct Kcnj3 (KCNJ3) catalog mouse model, featuring conditional knockout and standard knockout. Researchers can order pre-developed catalog lines or request a custom mouse model, including humanized, knockin, and transgenic variations with verified germline transmission.
