- FunctionMay 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.
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.
- Tissue specificityPresent in cortical renal tubules (at protein level). Soluble peptide is present in serum and cerebrospinal fluid. Expressed in kidney, placenta, small intestine and prostate. Down-regulated in renal cell carcinomas, hepatocellular carcinomas, and in chronic renal failure kidney.
- Involvement in diseaseDefects in KL are a cause of hyperphosphatemic familial tumoral calcinosis (HFTC) [MIM:211900]. A severe metabolic disorder that manifests with hyperphosphatemia and massive calcium deposits in the skin and subcutaneous tissues. Some patients manifest recurrent, transient, painful swellings of the long bones associated with the radiographic findings of periosteal reaction and cortical hyperostosis and absence of skin involvement.
- Sequence similaritiesBelongs to the glycosyl hydrolase 1 family. Klotho subfamily.
- DomainContains 2 glycosyl hydrolase 1 regions. However, the first region lacks the essential Glu active site residue at position 239, and the second one lacks the essential Glu active site residue at position 872.
- Cellular localizationSecreted and Cell membrane. Isoform 1 shedding leads to a soluble peptide.

ab69208 staining Klotho in human kidney tissue sections by Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections). Tissue underwent fixation in formaldehyde, heat mediated antigen retrieval and blocking (5 minutes/peroxidase block and 10 minutes/protein block) for 15 minutes at 200C was performed. The primary antibody was diluted 1/250 and incubated with the sample for 45 minutes at 200C. A HRP conjugated goat polyclonal to rabbit IgG was used undiluted as secondary antibody.
