Anti-NEK9 antibodies are used in the immunodetection of the protein NIMA related kinase 9. In humans, the canonical protein has a reported length of 979 amino acid residues and a mass of 107.2 kDa. Its subcellular localization is in the nucleus and cytoplasm. It is notably expressed in the heart, liver, kidney and testis. A member of the NEK Ser/Thr protein kinase protein family, NEK9 is a reported pleiotropic regulator of mitotic progression, participating in the control of spindle dynamics and chromosome separation. The NEK9 gene has been associated with the disease, Lethal congenital contracture syndrome. Synonyms for this target antigen include NIMA (never in mitosis gene a)- related kinase 9, nercc1 kinase, nimA-related protein kinase 9, and serine/threonine-protein kinase Nek9. NEK9 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of NEK9 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. Immunofluorescence and Immunohistochemistry are also common applications.
