Why model F2
F2, ortholog of human F2, encodes prothrombin, the vitamin K dependent precursor of thrombin and the central protease of hemostasis. Prothrombinase, comprising factor Xa and factor Va on an anionic phospholipid surface, cleaves prothrombin at two sites to release the Gla and kringle containing fragment 1.2 and generate alpha-thrombin, whose substrate selection is governed by two electropositive exosites: exosite I engages fibrinogen, PAR1, and thrombomodulin, while exosite II binds heparin and GPIb alpha. Thrombin converts fibrinogen to fibrin, activates factors V, VIII, XI, and XIII along with platelet PAR1 and PAR4, and when bound to thrombomodulin switches specificity to activate protein C. Complete deficiency is lethal in mouse, with embryonic loss and neonatal hemorrhage, so hypomorphic or conditional alleles are mandatory. Note that the common human G20210A thrombophilia allele lies in the 3 prime untranslated region and raises expression rather than altering sequence, so dosage-increasing designs, not missense knockins, are the faithful mimic.

CKOCKO
These strains carry loxP sites flanking exon 3-4 of F2 gene. When crossed with a Cre recombinase-expressing strain, this strain is useful in eliminating tissue-specific conditional expression of F2 gene.

About F2 Mouse Model Types
A F2 knockout mouse has the F2 gene permanently inactivated, enabling loss of function studies. A F2 conditional knockout (floxed) mouse carries loxP sites flanking a critical exon of F2, allowing Cre recombinase dependent deletion in specific tissues or at specific timepoints.
