Rb2344-290414-WS

A synthetic peptide from aa region 390-440 of human Klotho conjugated to blue carrier protein was used as the antigen.

KL

FUNCTION: 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. Essential factor for the specific interaction between FGF23 and FGFR1.
The Klotho peptide generated by cleavage of the membrane-bound isoform maybe an anti-aging circulating hormone which would extend life span by inhibiting insulin/IGF1 signaling.
SUBCELLULAR LOCATION: Isoform 1: Cell membrane; Single-pass type I membrane protein. Note: Isoform 1 shedding leads to a soluble peptide.
Isoform 2: Secreted
Klotho peptide: Secreted
TISSUE SPECIFICITY: Present 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.

Maintain the lyophilised/reconstituted antibodies frozen at -20°C for long term storage and refrigerated at 2-8°C for a shorter term. When reconstituting, glycerol (1:1) may be added for an additional stability. Avoid freeze and thaw cycles.
