Protocols

Specificity / Sensitivity

GSK-3β (3D10) Mouse mAb recognizes endogenous levels of total GSK-3β protein. This antibody does not cross-react with GSK-3α.

Source / Purification

Monoclonal antibody is produced by immunizing animals with recombinant protein specific to the carboxy-terminus of human GSK-3β protein.

Western Blotting

Western Blotting

Western blot analysis of extracts from wild-type, GSK-3α (-/-), and GSK3β (-/-) mouse embryonic fibroblasts (MEFs) and HeLa cells using GSK-3β (3D10) Mouse mAb (upper) and GSK-3α/β (D75D3) XP® Rabbit mAb #5676 (lower). (MEF wild type, GSK-3α (-/-) and GSK-3β (-/-) cells were kindly provided by Dr. Jim Woodgett, University of Toronto, Canada).

Flow Cytometry

Flow Cytometry

Flow cytometric analysis of wild-type mouse embryonic fibroblasts (MEFs) (green) and GSK-3β (-/-) MEFs (blue) using GSK-3β (3D10) Mouse mAb. (MEF wild type and GSK-3β (-/-) cells were kindly provided by Dr. Jim Woodgett, University of Toronto, Canada).

IF-IC

IF-IC

Confocal immunofluorescent analysis of wild-type mouse embryonic fibroblasts (MEFs) (left) and GSK-3β (-/-) MEFs (right) using GSK-3β (3D10) Mouse mAb (green). Red = Propidium Iodide/RNase (fluorescent DNA dye). (MEF wild type and GSK-3β (-/-) cells were kindly provided by Dr. Jim Woodgett, University of Toronto, Canada).


Background

Glycogen synthase kinase-3 (GSK-3) was initially identified as an enzyme that regulates glycogen synthesis in response to insulin (1). GSK-3 is a ubiquitously expressed serine/threonine protein kinase that phosphorylates and inactivates glycogen synthase. GSK-3 is a critical downstream element of the PI3K/Akt cell survival pathway whose activity can be inhibited by Akt-mediated phosphorylation at Ser21 of GSK-3α and Ser9 of GSK-3β (2,3). GSK-3 has been implicated in the regulation of cell fate in Dictyostelium and is a component of the Wnt signaling pathway required for Drosophila, Xenopus, and mammalian development (4). GSK-3 has been shown to regulate cyclin D1 proteolysis and subcellular localization (5).
