Abstract / Description of output
In this chapter, we will review some of the information regarding the functional significance of the inorganic phosphate (Pi)/pyrophosphate (PPi) ratio for physiological mineralization of hard tissues. We will recount the structure and function of the phosphatases involved in the regulation of this ratio: Tissue-nonspecific alkaline phosphatase (TNAP); Nucleotide Pyrophosphatases/Phosphodiesterase 1 (ENPP1); Na,K-ATPase; Nucleoside triphosphate diphosphohydrolase 1 (CD39); ecto-5′-nucleotidase (CD73) and orphan phosphatase 1 (PHOSPHO1); and how this knowledge has guided the development of protein therapeutics and of small molecule inhibitors to affect the Pi/PPi ratio in pathological conditions ranging from soft bones to ectopic calcification disorders.
