Mouse Monoclonal Antibody to MLL

Myeloid/lymphoid or mixed-lineage leukemia (trithorax homolog Drosophila). Eukaryotic RNA polymerase II mediates the synthesis of mature and functional messenger RNA. This is a multistep process called the transcription cycle that includes five stages: preinitiation promoter clearance elongation and termination. Elongation is thought to be a critical stage for the regulation of gene expression. ELL (11-19 lysine-rich leukemia protein also designated MEN) functions as an RNA polymerase II elongation factor that increases the rateof transcription by suppressing transient pausing by RNA polymerase II. Also ELL is thought to regulate cellular proliferation. ELL is abundantly expressed in peripheral blood leukocytes skeletal muscle placenta and testis and has lower expression in spleen thymus heart brain lung kidney liver and ovary. The gene encoding human ELL which maps to chromosome 19p13. 1 is one of several genes which undergo translocation with the MLL gene on chromo-some 11q23 in acute myeloid leukemia. MLL (myeloid/lymphoid leukemia also designated ALL-1 and HRX) is a 430 kDa protein that regulates embryonal and hematopoietic development.
