Abstract:
Background
Protein Ser/Thr phosphatase 5 (PP5) and its Saccharomyces cerevisiae homolog protein phosphatase T1 (Ppt1p) each contain an N-terminal domain consisting of several tetratricopeptide repeats
(TPRs) and a C-terminal catalytic domain that is related to the catalytic subunits of protein phosphatases 1 and 2A, and calcineurin.
Analysis of yeast Ppt1p could provide important clues to the function of PP5 and its homologs, however it has not yet been
characterized at the biochemical or cellular level.
