Cox6A1 Gene is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
Cytochrome c oxidase subunit 6A1 (COX6A1) is a nuclear-encoded mitochondrial protein that is a subunit of cytochrome c oxidase (complex IV) in the electron transport chain. The COX6A1 gene is located on chromosome 17q24.2 and encodes a protein of 97 amino acids. COX6A1 is expressed in tissues with high oxidative metabolism including heart, skeletal muscle, and brain. In neurons, COX6A1 supports aerobic respiration and ATP production. Mutations in COX6A1 cause Leigh syndrome and cardiomyopathy, highlighting its essential role in mitochondrial energy production. The enzyme's activity can be regulated by nitric oxide and oxygen levels, linking cellular respiration to tissue oxygen supply.
Cytochrome c oxidase subunit 6A1 (COX6A1) is a nuclear-encoded subunit of mitochondrial complex IV (cytochrome c oxidase). COX6A1 is one of the smaller subunits and plays a structural role in the assembly and function of the complex.
