• "These calcium ion channels can be closed by the action of an enzyme called phosphoprotein phosphatase which dephosphorylates the proteins."
• "Preclinical studies also suggest that Vimpat® binds to the collapsin response mediator protein-2 (CRMP-2), a phosphoprotein which is mainly expressed in the nervous system and is involved in neuronal differentiation and control of axonal outgrowth."
• "The observed correlation would appear to be significantly higher than random if we allow the random phosphorylation sites to be drawn from any phosphoprotein without constraining the number of phosphorylation sites in each specific protein blue curve."
