TULA-2 protein phosphatase suppresses activation of Syk through the GPVI platelet receptor for collagen by dephosphorylating Tyr(P)346, a regulatory site of Syk.

There was a typographic error found in one of the peptide sequences listed under “Experimental Procedures” (“Phosphatase Assay” section). The N-terminal sequences of all three peptides should be MDT (MetAsp-Thr) as correctly indicated for the first two peptides, and not MTD (Met-Thr-Asp) as erroneously indicated in the third. This error does not affect the results or conclusions of this work.
