Mitosin Mouse anti-Human, Unlabeled, Clone: 11, BD

Mitosin, a nuclear proetin of 3113 amino acids, contains a pair of tandem repeats and seven leucine repeats. In vitro, Mitosin directly interacts with the retinoblastoma protein, Rb. Mitosin is expressed throughout the cell cycle, with levels being lowest during G1, and it localizes at the kinetochore during the mitotic phase. The subcellular redistribution of Mitosin to the kinetochore is linked to its phosphorylation. Its expression is linked to patients with autoimmune diseases characterized by abnormal cell proliferation. Ectopic expression of a truncated version of Mitosin blocks the progression of the cell cycle. This suggests that the protein has an important role during cell proliferation. Because of similarities in subcellular localization and expression, Mitosin and the autoantigen p300/CENP-F, which is also linked to a multitude of autoimmune disorders, are probably the same protein.
