Functions
PTPN1 is perhaps the best understood classical PTP. It is a critical negative regulator of insulin and leptin signaling, as well as other receptor tyrosine kinases and cytokine receptors, and is known to undergo reversible oxidation (see review [1]). Recently, it has been reported that inactivation of PTP1B by reactive oxygen species is essential for oncogene-induced senescence (OIS), which prevents the progression of preneoplastic cells harboring oncogenic mutations [2].
