Description
SpecificityThis antibody recognizes mitosin, a 350 kD phosphoprotein that is specifically involved in mitotic-phase progression. Mitosin is expressed throughout S, G2, and M phases of the cell cycle, but is absent in G0 and G1. It associates with the mitotic apparatus during M-phase and is redistributed from the nucleus to the centromere, spindle, and midbody during M-phase progression. Its usefulness as a proliferation marker is under active investigation.
FunctionRequired for kinetochore function and chromosome segregation in mitosis. Required for kinetochore localization of dynein, LIS1, NDE1 and NDEL1. Regulates recycling of the plasma membrane by acting as a link between recycling vesicles and the microtubule network though its association with STX4 and SNAP25. Acts as a potential inhibitor of pocket protein-mediated cellular processes during development by regulating the activity of RB proteins during cell division and proliferation. May play a regulatory or permissive role in the normal embryonic cardiomyocyte cell cycle and in promoting continued mitosis in transformed, abnormally dividing neonatal cardiomyocytes. Interaction with RB directs embryonic stem cells toward a cardiac lineage. Involved in the regulation of DNA synthesis and hence cell cycle progression, via its C-terminus. Has a potential role regulating skeletal myogenesis and in cell differentiation in embryogenesis. Involved in dendritic cell regulation of T-cell immunity against chlamydia. {PubMed:12974617, PubMed:17600710, PubMed:7542657, PubMed:7651420}.
