Anti-HOX1J antibodies enable researchers to detect and measure the HOX1J antigen in biological samples. This target is a reported synonym of the HOXA13 gene, which encodes homeobox A13. This protein is known to function in ear development, among other biological roles. The human version of HOX1J has a canonical amino acid length of 388 residues and a protein mass of 39.7 kilodaltons. It is reported to be localized in the nucleus of cells. This target antigen may also be known as HOX1.
