Cardiolipin peroxidase does not refer to a specific enzyme but rather encompasses enzymes capable of catalyzing the peroxidation of cardiolipin, a specific phospholipid. These enzymes are typically associated with the mitochondrial membrane, as cardiolipin is predominantly found in the inner mitochondrial membrane. In cells, cardiolipin peroxidases are involved in regulating mitochondrial function, including energy metabolism, cell apoptosis, and mitochondrial membrane integrity. Cardiolipin peroxidation can lead to mitochondrial dysfunction and is associated with various diseases, including heart disease, neurodegenerative diseases, and metabolic disorders. The specific expression and mutation patterns of genes involved in cardiolipin peroxidase are not well understood, as it involves a variety of enzymes and pathways rather than a single enzyme.
