DUSP3 Shows activity both for tyrosine-protein phosphate and serine-protein phosphate, but displays a strong preference toward phosphotyrosines. Specifically dephosphorylates and inactivates ERK1 and ERK2. Belongs to the protein-tyrosine phosphatase family. Non-receptor class dual specificity subfamily. 2 alternatively spliced human isoforms have been reported. Note: This description may include information from UniProtKB.
