Protein phosphorylation is a reversible post-translational modification carried out by two families of enzymes, Protein Kinases and Protein Phosphatases. The interplay between these two families of enzymes is responsible for modulating the phosphorylation state of their physiological substrates, and thereby their activities, subcellular localization and interactions with other proteins. Similar to Protein Kinases, Protein Phosphatases play pivotal roles in a myriad of biological processes including cell growth, proliferation, survival, and apoptosis. Protein Phosphatases are broadly categorized according to specific amino acids they dephosphorylate into two major families: protein serine/threonine phosphatases, and protein tyrosine phosphatases, which also include the dual-specificity phosphatases.

SignalChem, with comprehensive active Protein Kinase product line, has utilized our expertise in the recombinant protein production to manufacture biologically active phosphatases including PP1s, PP2s, PTPNs, and more. An in-house product development team with over 100 years of combined experience in protein biochemistry is behind the production and quality control of all the phosphatases as well as the method development for their activity assays. We aim to manufacture our phosphatases with superior quality and activity to facilitate and assist the global research and drug discovery efforts aiding human health.
