Similar to thyroid hormones, the calcineurin/NFAT pathway regulates bone mass via its actions in osteoblasts and by indirect effects on osteoclast function. Calcineurin is a calcium- and calmodulin-activated phosphatase that dephosphorylates the transcription factor NFAT enabling its translocation to the nucleus. RCAN2 is an inhibitor of calcineurin that is stimulated by T3 in brain, heart and skeletal muscle although its expression in bone has not been studied. Thu...
