HUMAN ERYTHROCYTE CATALASEHUMAN ERYTHROCYTE CATALASE

DiseaseDisease

[CATA_HUMAN] Defects in CAT are the cause of acatalasemia (ACATLAS) [MIM:614097]. A metabolic disorder characterized by absence of catalase activity in red cells and is often associated with ulcerating oral lesions.^[1]

FunctionFunction

[CATA_HUMAN] 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.^[2]
