Fgf21, the mouse ortholog of human FGF21, encodes an endocrine FGF whose weak heparan sulfate affinity permits circulation and whose activity requires the coreceptor beta-Klotho paired with FGFR1c on adipocytes, or FGFR1c in hypothalamus and hindbrain. Hepatic transcription is induced by PPARalpha during fasting and ketogenesis and by ATF4 during amino acid restriction and integrated stress response, and the protein raises adipose glucose uptake and adiponectin, promotes energy expenditure, and centrally suppresses sweet and alcohol preference while stimulating water intake. Circulating levels are limited by fibroblast activation protein cleavage, a fact exploited by protease-resistant analogs including efruxifermin and pegozafermin. Nulls are viable, so constitutive deletion suits metabolic challenge protocols, while conditional floxed alleles distinguish hepatocyte-derived from adipose or muscle sources and Klb conditionals localize the responsive tissue. No paralog substitutes because beta-Klotho dependence is specific, though FGF15 and FGF19 share the coreceptor with FGFR4. Humanized knockins are the appropriate platform for analog pharmacokinetics and receptor-selectivity endpoints.
ingenious targeting laboratory offers 3 distinct Fgf21 (FGF21) catalog mouse models in the FGF family, 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.

Order catalog modelA Fgf21 knockout mouse has the Fgf21 gene permanently inactivated, enabling loss of function studies. A Fgf21 conditional knockout (floxed) mouse carries loxP sites flanking a critical exon of Fgf21, allowing Cre recombinase dependent deletion in specific tissues or at specific timepoints.
