Bub3 (Paperback)

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Mitotic checkpoint protein BUB3 is a protein that in humans is encoded by the BUB3 gene.Bub3 is a protein involved with the regulation of the Spindle Assembly Checkpoint (SAC); though BUB3 is non-essential in yeast, it is essential in higher eukaryotes. As one of the checkpoint proteins, Bub3 delays the irreversible onset of anaphase through direction of kinetochore localization during prometaphase to achieve biorentation.
