Anti-MAX dimerization protein MLX antibodies are used for the immunodetection of the protein encoded by the MLX gene. In humans, the canonical protein has a reported length of 298 amino acid residues and a mass of 33.3 kDa. Its subcellular localization is in the cytoplasm. Alternative splicing is reported to yield 3 different isoforms for this protein. It is reported to be expressed in all tissues tested, including spleen, thymus, prostate, ovary, intestine, colon, peripheral blood leukocyte, heart, liver, skeletal muscle and kidney. It is noted to be involved in the regulation of transcription. Other names for this target antigen include MXD7, TCFL4, TF4, bHLHd13, max-like protein X, BigMax protein, MAX-like bHLHZIP protein, and MAD7. Gene orthologs have been identified in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species.
