WebbThe protein tyrosine phosphatase, nonreceptor type 1 (PTP1b) and the phosphatase and tensin homolog (PTEN) are two phosphatases that attenuate insulin signals at early points in the pathway. PTP1B reduces insulin sensitivity because it dephosphorylates the insulin receptor and the IRS proteins. WebbPlant protein phosphatases are predominantly protein serine⁄threonine phosphatases that belong to the three classes: phosphoprotein phos-phatases, phosphoprotein metallophosphatases and aspartate-based protein phosphatases [1].
