The scaffolding A/Tpd3 subunit and high phosphatase activity are dispensable for Cdc55 function in the Saccharomyces cerevisiae spindle checkpoint and in cytokinesis.

The Journal of biological chemistry - 19 Nov 2004

Abstract excerpt

Protein serine/threonine phosphatase 2A (PP2A) is a multifunctional enzyme whose trimeric form consists of a scaffolding A subunit, a catalytic C subunit, and one of several regulatory B subunits (B, B', and B''). The adenovirus E4orf4 protein associates with PP2A by directly binding the B or B' subunits. An interaction with an active PP2A containing the B subunit, or its homologue in yeast, Cdc55, is required...
