Anti-IQCG antibodies are used in the immunodetection of the protein IQ motif containing G. In humans, the canonical protein has a reported length of 443 amino acid residues and a mass of 51.9 kDa. Its subcellular localization is in the cytoplasm. Up to 2 different isoforms have been reported for this protein. It is notably expressed in the bronchus and fallopian tube. A member of the DRC9 protein family, IQCG is a known component of the nexin-dynein regulatory complex (N-DRC), a key regulator of ciliary/flagellar motility which maintains the alignment and integrity of the distal axoneme and regulates microtubule sliding in motile axonemes. Synonyms for this target antigen include IQ domain-containing protein G, dynein regulatory complex subunit 9, and dynein regulatory complex protein 9. IQCG gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Some IQCG antibodies may have been used in research and have associated citations. Immunofluorescence is a widely used application for these antibodies. ELISA, Western Blot, and Immunohistochemistry are also common applications.
