Phosphate-regulating neutral endopeptidase PHEX (PHEX)

Peptidase that cleaves SIBLING (small integrin-binding ligand, N-linked glycoprotein)-based ASARM peptides, thus regulating their biological activity (PubMed:9593714, PubMed:15664000, PubMed:18162525, PubMed:18597632). Cleaves ASARM peptides between Ser and Glu or Asp residues (PubMed:18597632).

Regulates osteogenic cell differentiation and bone mineralization through the cleavage of this MEPE-derived ASARM peptide (PubMed:18597632). Promotes dentin mineralization and renal phosphate reabsorption by cleaving DMP1- and MEPE-derived ASARM peptides (PubMed:18597632, PubMed:18162525).
