Ligand Sp. Action Value Parameter Reference
tectorigenin Small molecule or natural product Ligand has a PDB structure Ma Activation - - 11
Description: Activation of catalase in V79-4 cell in culture.
Antibody Comments
Anti-catalase single-domain antibodies were shown to block catalase-mediated H2O2 breakdown in human tumour cells with the effect of reactivating reactive oxygen species-dependent apoptosis [1]. These antibodies inhibited tumour growth in human tumor xenografts, and the effect was strongly synergistic with paclitaxel chemotherapy.

Clinically-Relevant Mutations and Pathophysiology Click here for help
Disease:  Acatalasemia
Description: A rare autosomal recessive peroxisomal disorder caused by deficient activity of the enzyme, catalase, that was originally identified in patients suffering from ulcerating oral gangrene. different A number of CAT gene mutations that generate enzymes with varying degress of enzymatic deficiency have been identified. Heterozygotes have an intermediate level of catalase in the blood.
Synonyms: acatalasia
catalase deficiency
Takahara disease
OMIM: 614097
Orphanet: ORPHA926

General Comments
Catalase is a key antioxidant enzyme that protects cells from oxidative stress by neutralising the toxic effects of hydrogen peroxide. It is located in the peroxisomes of nearly all aerobic cells.
As catalase activity is associated with cytoprotective effects [9], it may be a potential molecular target whose pharmacological modulation could mediate anti-apoptotic functions [11]. Catalase has been implicated in many pathophysiological processes of human diseases, including cancer [3,5]. In tumours, cancer cells may be chronically exposed to oxidative stressors such as hydrogen peroxide in the hypoxic tumour microenvironment, and undergo cellular adaptation (redox adaptation, altered expression of antioxidant enzymes) that allows them to maintain proliferative advantage, but also leaves them sensitive to an oxidant insult. Understanding the molecular mechanisms (e.g. transcription factors, genetic, epigenetic, and posttranscriptional processes) controlling catalase expression will aid future development of novel pro-oxidant cancer chemotherapy [2].
