Identification
HMDB Protein ID CDBP04048
Secondary Accession Numbers Not Available
Name Dual specificity protein phosphatase 18
Description Not Available
Synonyms
  1. LMW-DSP20
  2. Low molecular weight dual specificity phosphatase 20
Gene Name DUSP18
Protein Type Enzyme
Biological Properties
General Function Involved in phosphatase activity
Specific Function Can dephosphorylate single and diphosphorylated synthetic MAPK peptides, with preference for the phosphotyrosine and diphosphorylated forms over phosphothreonine. In vitro, dephosphorylates p-nitrophenyl phosphate (pNPP).
