Overview
catalase 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. Homotetramer. Belongs to the catalase family. Note: This description may include information from UniProtKB.

Cellular Component: Golgi apparatus; peroxisomal membrane; peroxisomal matrix; endoplasmic reticulum; lysosome; plasma membrane; mitochondrial intermembrane space; peroxisome; cytosol
Molecular Function: antioxidant activity; oxidoreductase activity, acting on peroxide as acceptor; enzyme binding; protein homodimerization activity; catalase activity; metal ion binding; heme binding; NADP binding; receptor binding; aminoacylase activity
Biological Process: cholesterol metabolic process; nucleobase, nucleoside and nucleotide metabolic process; hemoglobin metabolic process; menopause; purine base metabolic process; protein homotetramerization; activation of NF-kappaB transcription factor; positive regulation of phosphoinositide 3-kinase cascade; response to vitamin E; response to reactive oxygen species; triacylglycerol metabolic process; response to hyperoxia; UV protection; hydrogen peroxide catabolic process; inhibition of NF-kappaB transcription factor; positive regulation of cell division; aerobic respiration; response to hypoxia; purine nucleotide catabolic process; protein tetramerization; negative regulation of apoptosis
