Research Backgrounds

Function:

Involved in the suppression of bile acid biosynthesis through down-regulation of CYP7A1 expression, following positive regulation of the JNK and ERK1/2 cascades. Stimulates glucose uptake in adipocytes. Activity requires the presence of KLB and FGFR4.

Subcellular Location:

Secreted.

Extracellular region or secreted Cytosol Plasma membrane Cytoskeleton Lysosome Endosome Peroxisome ER Golgi apparatus Nucleus Mitochondrion Manual annotation Automatic computational assertionSubcellular location
Tissue Specificity:

Expressed in fetal brain, cartilage, retina, and adult gall bladder.

Subunit Structure:

Interacts with FGFR1, FGFR2, FGFR3 and FGFR4. Affinity between fibroblast growth factors (FGFs) and their receptors is increased by KL, KLB and heparan sulfate glycosaminoglycans that function as coreceptors. Interacts with KL; this interaction is direct. Interacts with KLB; this interaction is direct. Interacts with FGFR4 in the presence of heparin, KL or KLB. Interacts with MALRD1.

Family&Domains:

Belongs to the heparin-binding growth factors family.

Application: IHC    Species: Human    Sample: ileum tissue

Fig. 5 Expression of FGF19 of the terminal ileum in chronic diar- rhoea patients. a, b A positive immunoperoxidase reaction was observed in the cytoplasmatic compartment of terminal ileum mucosa epithelial cells, and some gland cells in the lamina propria. Ileum enterocytes showed FGF19 signal from apical to basal domains, espe-cially in the apical domains. c, d The staining intensity was divided into 2 categories (c pale brown = 1; d brown = 2). e–g The percentage of immunoreactive cells were calculated and classified on a 3-point scale (e 1–33% = 1; f 34–66% = 2; g 67–100% = 3)
