Product Description	Recombinant Human Beta Klotho Protein is expressed from HEK293 with His tag at the C-Terminus.It contains Met30-Thr983.
Product Background	Beta-klotho (KLB) is a coreceptor required for endocrine fibroblast growth factor (FGF) 15/19 and FGF21 signaling in the brain. Klb is prominent within the hypothalamus, which is consistent with its metabolic functions, but diverse roles for Klb are now emerging. Central Klb expression is low but discrete and may govern FGF-targeted sites.
Product Category	Recombinant Protein / Antibody discovery

Protein	Beta Klotho
Synonyms	betaKlotho; beta-klotho; BKL; KLB; klotho beta like; Klotho beta; MGC142213;βKlotho; β-klotho; klotho β like; Klotho β
Accession	Q86Z14
Species	Human
