Manganese is considered to be the 12th most abundant element in the biosphere. Its concentration in the Earth's crust reaches as much as mass %. The concentration of manganese in the ocean crust is about 60% greater than that in the continental one [70]. It is widely distributed in soil, sediment, water and in biological materials.
Various mutations in leucinerich repeat kinase 2 (LRRK2) have been linked to susceptibility for both familial and idiopathic lateonset Parkinson's disease (PD). In this study, we have demonstrated that phosphorylation of MBP and LRRKtide by the LRRK2 G2019S mutant was activated by Mn2+ in vitro. This enhanced G2019S kinase activity was due to the combination of an increase in kinase and a ...
