Abstract excerpt
This study examined the role of calcineurin, a major calcium-dependent protein phosphatase, in dephosphorylating Ser-9 and activating glycogen synthase kinase-3beta (GSK-3beta). Treatment with calcineurin inhibitors increased phosphorylation of GSK-3beta at Ser-9 in SH-SY5Y human neuroblastoma cells. The over-expression of a constitutively active calcineurin mutant, calcineurin A beta (1-401), led to a...
