Title GL2 EXPRESSION MODULATOR, a plant specific protein phosphatase one interactor that binds phosphoinositides.
Journal Biochem Biophys Res Commun
Abstract Protein phosphatase one (PP1) is a major eukaryotic serine/threonine protein phosphatase whose activity is controlled by targeting or regulatory subunits. Currently, very few plant protein phosphatase one regulatory subunits are known. Here, Arabidopsis GL2 EXPRESSION MODULATOR (GEM) was identified and confirmed as a protein phosphatase one binding partner. GEM is a phosphoprotein, contains a highly conserved phosphoinositide binding GRAM domain and a classic protein phosphatase one binding RVXF motif. Lipid overlays show GEM has the ability to interact with phosphoinositides through its GRAM domain. GEM is the first plant specific protein phosphatase one interactor to be discovered.
