A positive role for the PP2A catalytic subunit in Wnt signal transduction.

Abstract

Protein phosphatase-2A (PP2A) is a multisubunit serine/threonine phosphatase involved in intracellular signaling, gene regulation, and cell cycle progression. Different subunits of PP2A bind to Axin and Adenomatous Polyposis Coli, components of the Wnt signal transduction pathway. Using early Xenopus embryos, we studied how PP2A functions in Wnt signal… (More)
