Anti-CCDC9 antibodies are used in the immunodetection of the protein coiled-coil domain containing 9. In humans, the canonical protein has a reported length of 531 amino acid residues and a mass of 59.7 kDa. It is notably widely expressed in many tissue types. CCDC9 is a suspected component of the exon junction complex (EJC), a multiprotein complex that associates immediately upstream of the exon-exon junction on mRNAs and serves as a positional landmark for the intron exon structure of genes and directs post-transcriptional processes in the cytoplasm such as mRNA export, nonsense-mediated mRNA decay (NMD) or translation. Synonyms for this target antigen include coiled-coil domain-containing protein 9. CCDC9 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Western Blot is the most common application for the CCDC9 antibodies listed below. Immunocytochemistry and Immunofluorescence are also common applications.
