|Calculated MW||17 KDa|
|Other Names||Cytochrome c oxidase subunit 4 isoform 1, mitochondrial, Cytochrome c oxidase polypeptide IV, Cytochrome c oxidase subunit IV isoform 1, COX IV-1, Cox4i1, Cox4, Cox4a|
|Target/Specificity||Synthetic phospho-peptide corresponding to amino acid residues surrounding Ser58 conjugated to KLH.|
|Format||Prepared from rabbit serum by affinity purification via sequential chromatography on phospho- and dephosphopeptide affinity columns.|
|Antibody Specificity||Specific for the ~17k COXIV-1 protein phosphorylated at Ser58. Immunolabeling is blocked by the phospho-peptide used as antigen but not by the corresponding dephospho-peptide.|
|Storage||Maintain refrigerated at 2-8°C for up to 6 months. For long term storage store at -20°C in small aliquots to prevent freeze-thaw cycles.|
|Precautions||Phospho-Ser58 COXIV Antibody is for research use only and not for use in diagnostic or therapeutic procedures.|

COX, also known as cytochrome c oxidase, has 12 subunits that make up the transmembrane mitochondrial protein. Subunit IV has two isoforms; COXIV-1 and COXIV-2 (Huttermann et al., 2001). COXIV-1 is expressed ubiquitously while COXIV-2 is highly expressed in adult lung and low levels in brain and heart (Huttermann et al., 2001). Phosphorylation of amino acid residue ser58 of the COXIV-1 protein is a PKA-dependent regulation of COX and plays an important role in metabolism and CREB cycle activation (Acin-Perez et al., 2011).
