CRYSTAL STRUCTURE OF THE PP2A PHOSPHATASE ACTIVATOR YPA2 PTPA2

The structure was published by Leulliot, N., Vicentini, G., Jordens, J., et al., Barford, D., Van Tilbeurgh, H., and Goris, J., in 2006 in a paper entitled "Crystal Structure of the Pp2A Phosphatase Activator: Implications for its Pp2A-Specific Ppiase Activity" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.8 Å and deposited in 2006.

The experimental data on which the structure is based was also deposited.
