Anti-Homeobox antibodies enable researchers to detect and measure the Homeobox antigen in biological samples. This target is a reported synonym of the LBX1 gene, which encodes ladybird homeobox 1. This protein is known to function in the morphogenesis of anatomical structure and cell proliferation, among other biological roles. The human version of Homeobox has a canonical amino acid length of 281 residues and a protein mass of 30.2 kilodaltons. It is reported to be localized in the nucleus of cells. Other names for this target antigen include CCHS3, HPX-6, and HPX6.
