The blots were produced using a 4-12% Bis-tris gel under the MOPS buffer system. The gel was run at 200V for 60 minutes before being transferred onto a Nitrocellulose membrane at 30V for 70 minutes. The membrane were blocked for an hour before being incubated with ab181373 (rabbit anti-Klotho antibody; diluted 5 ug/ml) for 24 hours at 4°C. Antibody binding was detected using infrared labelled goat anti-rabbit (green) antibody at 1 : 10,000 dilutions for 1 hour at room temperature before imaging.

Immunogen

The exact immunogen used to generate this antibody is proprietary information.

Specificity

When we tested the antibody in human samples, the only form of the protein that we are able to detect is the secreted one (about 65kDa). When we tested the antibody in mouse samples (wt vs KO) we could only detect the membrane bound form of the protein (about 130kDa). This difference could be due to the nature of the samples (different species). However, we do not have a clear explanation about this. Abcam welcomes customer feedback and would appreciate any comments regarding this product and the data presented here.

Supplementary information

Klotho also known as alpha Klotho protein is a multifunctional protein prominently involved in regulating aging processes. It consists of approximately 130 kDa and is expressed mainly in the kidneys brain and parathyroid gland. This membrane-bound protein may also exist in a soluble form after cleavage by specific enzymes. Alpha Klotho functions as a co-receptor for fibroblast growth factor 23 (FGF23) facilitating phosphate and vitamin D metabolism regulation.
Biological function summary

Alpha Klotho influences several cellular processes such as aging and mineral ion homeostasis. As a part of the FGF23-Klotho complex it enables the fibroblast growth factor to exert its biological effects. This protein modulates the effects of FGF23 on the renal excretion of phosphate and the synthesis of vitamin D. By interacting with FGF23 alpha Klotho supports maintaining electrolyte balance vital for proper physiological functioning.

Pathways

The FGF23-Klotho axis integrates into significant signaling pathways regulating mineral metabolism and aging. Klotho protein interactions with FGF23 contribute to controlling phosphate homeostasis by inhibiting renal phosphate reabsorption and suppressing vitamin D synthesis. It also engages with other proteins notably the fibroblast growth factors to regulate aging-related pathways ensuring cellular longevity and repair mechanisms are optimized.

Understanding Klotho's role helps in managing conditions like chronic kidney disease and some neurological disorders. Research indicates that reduced levels of alpha Klotho may correspond to kidney dysfunction due to its critical role in mineral metabolism. Furthermore alterations in Klotho expression connect with neurodegenerative diseases implicating its interaction with other proteins such as amyloid precursor protein and tau which are significant in disorders like Alzheimer's disease.

Target data

May have weak glycosidase activity towards glucuronylated steroids. However, it lacks essential active site Glu residues at positions 239 and 872, suggesting it may be inactive as a glycosidase in vivo. May be involved in the regulation of calcium and phosphorus homeostasis by inhibiting the synthesis of active vitamin D (By similarity). Essential factor for the specific interaction between FGF23 and FGFR1 (By similarity).. The Klotho peptide generated by cleavage of the membrane-bound isoform may be an anti-aging circulating hormone which would extend life span by inhibiting insulin/IGF1 signaling.
