  • Function

    Occurs in almost all aerobically respiring organisms and serves to protect cells from the toxic effects of hydrogen peroxide. Promotes growth of cells including T-cells, B-cells, myeloid leukemia cells, melanoma cells, mastocytoma cells and normal and transformed fibroblast cells.
  • Involvement in disease

    Defects in CAT are the cause of acatalasia (ACATLAS) [MIM:115500]; also known as acatalasemia. This disease is characterized by absence of catalase activity in red cells and is often associated with ulcerating oral lesions.
  • Sequence similarities

    Belongs to the catalase family.
  • Post-translational
    modifications

    The N-terminus is blocked.
  • Cellular localization

    Peroxisome.
  • Target information above from: UniProt accession P04040 The UniProt Consortium
    The Universal Protein Resource (UniProt) in 2010
    Nucleic Acids Res. 38:D142-D148 (2010) .
