  • Function

    Cytochrome c oxidase is the component of the respiratory chain that catalyzes the reduction of oxygen to water. Subunits 1-3 form the functional core of the enzyme complex. CO I is the catalytic subunit of the enzyme. Electrons originating in cytochrome c are transferred via the copper A center of subunit 2 and heme A of subunit 1 to the bimetallic center formed by heme A3 and copper B.
  • Pathway

    Energy metabolism; oxidative phosphorylation.
  • Involvement in disease

    Defects in MT-CO1 are a cause of Leber hereditary optic neuropathy (LHON) [MIM:535000]. LHON is a maternally inherited disease resulting in acute or subacute loss of central vision, due to optic nerve dysfunction. Cardiac conduction defects and neurological defects have also been described in some patients. LHON results from primary mitochondrial DNA mutations affecting the respiratory chain complexes.
    Defects in MT-CO1 are a cause of anemia sideroblastic acquired idiopathic (AISA) [MIM:516030]; a disease characterized by inadequate formation of heme and excessive accumulation of iron in mitochondria.
    Defects in MT-CO1 are a cause of mitochondrial complex IV deficiency (MT-C4D) [MIM:220110]; also known as cytochrome c oxidase deficiency. A disorder of the mitochondrial respiratory chain with heterogeneous clinical manifestations, ranging from isolated myopathy to severe multisystem disease affecting several tissues and organs. Features include hypertrophic cardiomyopathy, hepatomegaly and liver dysfunction, hypotonia, muscle weakness, excercise intolerance, developmental delay, delayed motor development and mental retardation. A subset of patients manifest Leigh syndrome.
    Defects in MT-CO1 are associated with recurrent myoglobinuria mitochondrial (RM-MT) [MIM:550500]. Recurrent myoglobinuria is characterized by recurrent attacks of rhabdomyolysis (necrosis or disintegration of skeletal muscle) associated with muscle pain and weakness, and followed by excretion of myoglobin in the urine.
    Defects in MT-CO1 are a cause of deafness sensorineural mitochondrial (DFNM) [MIM:500008]. DFNM is a form of non-syndromic deafness with maternal inheritance. Affected individuals manifest progressive, postlingual, sensorineural hearing loss involving high frequencies.
    Defects in MT-CO1 are a cause of colorectal cancer (CRC) [MIM:114500].

    I am sorry for the delay in getting back to you.

    I have now checked the other antibodies we have against this target and unfortunately none would be predicted to cross react with the Drosophila protein except the rabbit polyclonal ab90668. However there have been some problem in the production of this antibody and we are currently not expecting it to be back in stock until Spring 2013.

    I am sorry that I could not be of more help in this instance. You may be interested to review the antibodies we have which have shown cross reactivity with Drosophila proteins:


    If I can be of any further assistance, please do not hesitate to let me know.

    Thank you for contacting us. These antibodies are indeed raised in mouse and these antibodies will work better in human, mouse, rat cells and tissue sections. In case you are planning to use these antibodies on mouse tissue sections then we would recommend following additional blocking steps as given in the attached document https://www.abcam.com/index.html?pageconfig=resource&rid=11465 We do have anti MTCO1 antibodies that are raised in Rabbit. The catalogue numbers are ab45918; https://www.abcam.com/MTCO1-antibody-Mitochondrial-Marker-ab45918.html And ab90668; https://www.abcam.com/MTCO1-antibody-ab90668.html I hope this information is helpful to you. Please do not hesitate to contact us if you need any more advice or information.
