Phospho-Ser58 COXIV Antibody

Affinity purified rabbit polyclonal antibody

  • WB - Phospho-Ser58 COXIV Antibody AN1212
    Western blot of rat mitochondrial lysate showing specific immunolabeling of the ~17k COXIV phosphorylated at Ser58 (Control). Immunolabeling is blocked by the phospho-peptide used as antigen (Peptide) but not by the corresponding dephospho-peptide (not shown).

Gene Name COX4i1
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.
Dilution WB~~ 1:1000
Format Prepared from rabbit serum by affinity purification via sequential chromatography on phospho- and dephosphopeptide affinity columns.

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).
