General Information of Binding Target of SBP (BTS) (ID: ST00074)
BTS Name
Beta-klotho
Synonyms
BKL; BetaKlotho; Klotho beta-like protein
BTS Type
Protein
Family
Glycosyl hydrolase 1 family;
Klotho subfamily
Gene Name
KLB
Organism
Homo sapiens (Human)
Function
Contributes to the transcriptional repression of cholesterol 7-alpha-hydroxylase (CYP7A1), the rate-limiting enzyme in bile acid synthesis. Probably inactive as a glycosidase. Increases the ability of FGFR1 and FGFR4 to bind FGF21 (By similarity).
