NATA1, or Dual specificity phosphatase 26 (putative), is a human gene encoded by DUSP26. It may also be known as: Dual specificity protein phosphatase 26; Dual specificity phosphatase SKRP3; Low-molecular-mass dual-specificity phosphatase 4; DSP-4; LDP-4; Mitogen-activated protein kinase phosphatase 8; MAP kinase phosphatase 8; MKP-8; Novel amplified gene in thyroid anaplastic cancer; Dual specificity protein phosphatase 26 ; MKP8; SKRP3. The encoded protein is an enzyme with an amino acid length of 211 and a mass of 23.9 kDa. Other isoforms may exist. NATA1 is a member of the Protein-tyrosine phosphatase family, Non-receptor class dual specificity subfamily. Homologs of this gene exist in other organisms, including: Frog.
