Braf Knockin mouse models
Braf, the mouse ortholog of human BRAF, encodes the RAF family serine/threonine kinase that couples RAS-GTP to MEK1 and MEK2 through an N-terminal RAS binding domain and cysteine rich domain, an autoinhibitory 14-3-3 clamped conformation, and an obligate side-to-side kinase dimer interface. The V600E substitution within the activation segment mimics phosphorylation and signals as a RAS-independent monomer, whereas class II and class III alleles retain dimer or RAS dependence, a distinction that fully determines response to vemurafenib class inhibitors and explains paradoxical MAPK activation. Kinase-impaired germline variants instead drive cardiofaciocutaneous syndrome through altered dimer allostery. Constitutive null is embryonic lethal from vascular and placental failure, so conditional Lox-Stop-Lox V600E knockins driven by lineage-restricted Cre remain the standard for melanoma, thyroid, lung and colon models. Araf and Raf1 dimerize with BRAF and mediate resistance, so consider compound alleles. Match allele class to the inhibitor question, since monomer and dimer alleles predict opposite pharmacology.
Targeting Braf preserves positional context compared with viral or BAC approaches. That helps when you quantify expression or map chromatin.

Why this approach
Knockin and humanized formats keep regulatory context at the endogenous locus. For your target tissue focused programs, that matters when expression timing, splice isoforms, or allele dosage drive biology. Random integration transgenics can still help, but targeted alleles usually give cleaner pharmacology readouts.

FAQ
What Braf Knockin mouse models are available?
When Braf Knockin 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 Braf knockout embryonic lethal in mice?
It depends on background and allele design. Some Braf 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 Braf 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 Braf?
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.
