Function[DUSP_VAR67] Serine/Tyrosine phosphatase which down-regulates cellular antiviral response by dephosphorylating activated host STAT1 and blocking interferon (IFN)-stimulated innate immune responses. Dephosphorylates the A17 protein (By similarity). Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf.
