Glycogen synthase kinase-3 and the Alzheimer-like state of microtubule-associated protein tau
The Alzheimer-like state of tau protein includes phosphorylation by a proline-directed Ser/Thr kinase present in normal or pathological human brain. Extending earlier results on MAP kinase, we show here that the proline-directed kinase, GSK3, can induce an Alzheimer-like immune response involving several distinct and phoshorylatable epitopes at Ser—Pro motifs, as well as gel mobility shift, similar to MAP kinase. Both kinases behave like microtubule-associated proteins in that they co-purify through cycles of assembly and disassembly, and both kinases are directly associated with paired helical filaments
