研究背景

功能:

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.

翻译修饰:

N-glycosylated.

细胞定位:

Cell membrane>Single-pass type I membrane protein. Apical cell membrane>Single-pass type I membrane protein.
Note: Isoform 1 shedding leads to a soluble peptide.

组织特异性:

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.

亚基结构:

Homodimer. Interacts with FGF23 and FGFR1.

蛋白家族:

Contains 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.

Belongs to the glycosyl hydrolase 1 family. Klotho subfamily.
