Anti-LHX4 antibodies are used in the immunodetection of the protein LIM homeobox 4. In humans, the canonical protein has a reported length of 390 amino acid residues and a mass of 43.1 kDa. Its subcellular localization is in the nucleus. LHX4 is believed to play a critical role in the development of respiratory control mechanisms and in the normal growth and maturation of the lung. The LHX4 gene has been associated with the disease, Pituitary hormone deficiency. Synonyms for this target antigen include LIM/homeobox protein Lhx4 and LIM homeobox protein 4. LHX4 gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. Some LHX4 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
