basic FUNCTION	involved in catabolic pathway of activated oxygen species and free radical detoxification
	catalase overexpression has a protective role against UVB irradiation by preventing DNA damage mediated by the late ROS increase
	catalase is an antioxidant enzyme the activity of which is crucial for the protection against damage caused by reactive oxygen species
	heme enzymes, which catalyze decomposition of hydrogen peroxide to water and molecular oxygen
	is an important antioxidant enzyme that dismutates hydrogen peroxide into water and molecular oxygen
	catalase is a key enzyme in the metabolism of H2O2 and reactive nitrogen species, and its expression and localization is markedly altered in tumors
	major peroxisome protein, plays a critical role in removing peroxisome-generated reactive oxygen species (ROS) produced by peroxisome enzymes
	catalase plays an important role in pexophagy during nutrient deprivation
	potential therapeutic effects in nonalcoholic fatty liver disease (NAFLD) progression

INTERACTION

DNA

RNA

small molecule	cofactor,
	heme group and NADP

protein	transcription factors (PPARG,POU2F1), as well as genetic, epigenetic, and posttranscriptional processes, have emerged as crucial contributors to the regulation of catalase expression (PIMID: 26117330)
	MARVELD1 interacting with CAT regulates reactive oxygen species metabolism and mediates the sensitivity to chemotherapeutic drugs in epithelial tumors of the reproductive system

Variant & Polymorphism

Candidate gene	neurocognitive sequelae associated with radiation exposure can be reduced by overexpression of Mitochondrial CAT, operating through a mechanism involving the preservation of neuronal morphology
