Anti-myeloid/lymphoid or mixed-lineage leukemia (trithorax homolog, Drosophila) antibodies are used in antigen-specific immunodetection in biological samples. The target myeloid/lymphoid or mixed-lineage leukemia (trithorax homolog, Drosophila) is a known alias name of the protein lysine methyltransferase 2A, encoded by the KMT2A gene in humans. This 3969-amino acid residue protein is a known histone methyltransferase that plays an essential role in early development and hematopoiesis. It is localized to the nucleus of the cell and features methylated, cleaved and phosphorylated post-translational modifications. It is reported to be widely expressed in many tissue types. Other synonyms for myeloid/lymphoid or mixed-lineage leukemia (trithorax homolog, Drosophila) include ALL-1, ALL1, and CXXC7.
