Functions of B56-containing PP2As in Major Developmental and Cancer Signaling Pathways

Life Sci. 2010 Dec 18;87(23-26):659-66. doi: 10.1016/j.lfs.2010.10.003. Epub 2010 Oct 8.


Members of the B'/B56/PR61 family regulatory subunits of PP2A determine the subcellular localization, substrate specificity, and catalytic activity of PP2A in a wide range of biological processes. Here, we summarize the structure and intracellular localization of B56-containing PP2As and review functions of B56-containing PP2As in several major developmental/cancer signaling pathways.
