| 419512 | p38 MAPK | Protein | Homo sapiens-e | Phosphorylate | direct | MAPT | Protein | Homo sapiens-e | | | Phosphorylation sites on tau identified by
nanoelectrospray mass spectrometry: differences in vitro
between the mitogen-activated protein kinases ERK2, c-Jun
N-terminal kinase and P38, and glycogen synthase
kinase-3beta. / Their targets include the
microtubule-associated protein tau, which becomes
hyperphosphorylated in Alzheimer's disease./ Using
nanoelectrospray mass spectrometry, we have undertaken an
extensive comparison of phosphorylation in vitro by several
candidate tau kinases, namely, JNK, p38, ERK2, and glycogen
synthase kinase 3beta (GSK3beta). The three MAP kinases
phosphorylated Ser202 and Thr205 but not detectably Ser199,
whereas conversely GSK3beta phosphorylated Ser199 but not
detectably Ser202 or Thr205. Phosphorylated Ser404 was found
with all of these kinases except JNK. / The MAP kinases may
not be strictly proline specific: p38 phosphorylated the
nonproline sites Ser185, Thr245, Ser305, and Ser356, whereas
ERK2 was the most strict. / Thus, the three MAP kinases and
GSK3beta are importantly all strong candidates as tau
kinases that may be involved in the pathogenic
hyperphosphorylation of tau in Alzheimer's disease. | | | |
