+== Function ==
+[https://www.uniprot.org/uniprot/PP1A_HUMAN PP1A_HUMAN] Protein phosphatase that associates with over 200 regulatory proteins to form highly specific holoenzymes which dephosphorylate hundreds of biological targets. Protein phosphatase 1 (PP1) is essential for cell division, and participates in the regulation of glycogen metabolism, muscle contractility and protein synthesis. Involved in regulation of ionic conductances and long-term synaptic plasticity. May play an important role in dephosphorylating substrates such as the postsynaptic density-associated Ca(2+)/calmodulin dependent protein kinase II. Component of the PTW/PP1 phosphatase complex, which plays a role in the control of chromatin structure and cell cycle progression during the transition from mitosis into interphase. Regulates NEK2 function in terms of kinase activity and centrosome number and splitting, both in the presence and absence of radiation-induced DNA damage. Regulator of neural tube and optic fissure closure, and enteric neural crest cell (ENCCs) migration during development.<ref>PMID:17283141</ref>

+== Publication Abstract from PubMed ==
+Protein phosphatase-1 (PP1) drives a large amount of phosphoSer/Thr protein dephosphorylations in eukaryotes to counteract multiple kinases in signaling pathways. The phosphatase requires divalent metal cations for catalytic activity and contains iron naturally. Iron has been suggested to have an influence on PP1 activity through Fe(2+) and Fe(3+) oxidation states. However, much biochemical and all structural data have been obtained with recombinant PP1 containing Mn(2+) ions. Purifying iron-containing PP1 from Escherichia coli has thus far not been possible. Here, we present the preparation, characterization, and structure of iron-bound PP1alpha in inactive and active states. We establish a key role for the electronic/redox properties of iron in PP1 activity and shed light on the difference in substrate specificity between iron- and manganese-containing PP1.
