GSK3α is a multifunctional protein serine kinase, homologous to Drosophila 'shaggy' (zeste-white3) and implicated in the control of several regulatory proteins including glycogen synthase and transcription factors (e.g., JUN) (1). GSK3α also plays a role in the WNT and PI3K signaling pathways. Alzheimer disease is associated with increased production and aggregation of amyloid-beta-40 and -42 peptides into plaques. GSK3α is required for maximal production of the beta-amyloid-40 and -42 peptides generated from the amyloid precursor protein by presenilin-dependent gamma-secretase cleavage. In vitro, lithium, a GSK3α inhibitor, blocks the production of the beta-amyloid peptides by interfering with the gamma-secretase step (2).

Western blot of human GSK3a
GSK3a from other species may also be detectable.

Store at 4°C (add 0.1% NaN3) for several months, and at -20°C for longer periods. For optimal storage, aliquot target into smaller quantities after centrifugation and store at recommended temperature. For optimal performance, avoid repeated handling and multiple freeze/thaw cycles.
Representative western blot (1:1000) with Anti-GSK3α using 20 ng of GST-tagged human recombinant GSK3α and GSK3β.
