Anti-L3MBTL histone methyl-lysine binding protein 3 antibodies are used for the immunodetection of the protein encoded by the L3MBTL3 gene. In humans, the canonical protein has a reported length of 780 amino acid residues and a mass of 88.3 kDa. Its subcellular localization is in the nucleus. Alternative splicing is reported to yield 2 different isoforms for this protein. It is noted to be involved in chromatin organization and granulocyte differentiation. Other names for this target antigen include H-l(3)mbt-like protein 3, L3MBTL3, histone methyl-lysine binding protein, L3mbt-like 3, l(3)mbt-like 3, and lethal(3)malignant brain tumor-like protein 3. Gene orthologs have been identified in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species.
