| + | Saccharomyces cerevisiae tau55, a subunit of the RNA polymerase III-specific general transcription factor TFIIIC, comprises an N-terminal histidine phosphatase domain (tau55-HPD) whose catalytic activity and cellular function is poorly understood. We solved the crystal structures of tau55-HPD and its closely related paralogue Huf and used in silico docking methods to identify phospho-serine and phospho-tyrosine containing peptides as possible substrates that were subsequently validated using in vitro phosphatase assays. A comparative phospho-proteomic study identified additional phosphopeptides as possible targets, which show the involvement of these two phosphatases in the regulation of a variety of cellular functions. Our results identify tau55-HPD and Huf as bona fide protein phosphatases, characterize their substrate specificities and provide a small set of regulated phosphosite targets in vivo. | ||
