摘要: Abstract Maintaining the proper balance between osteoblast-mediated production of bone and its degradation by osteoclasts is essential for health. Osteoclasts are giant phagocytic cells that formed fusion monocyte-macrophage precursor cells; mature adhere to tightly secrete protons proteases degrade matrix. Phosphorylation tyrosine residues in proteins, which regulated biochemically-antagonistic activities protein kinases phosphatases (PTPs), central regulating their bone-resorbing activity. Here we review roles individual PTPs classical dual-specificity sub-families known support these processes (SHP2, cyt-PTPe, PTPRO, PTP-PEST, CD45) or inhibit them (SHP1, PTEN, MKP1). Characterizing functions complete molecular level understanding resorption designing novel therapeutic approaches treating disease.
