WARNING: Reagents contain sodium azide. Sodium azide is very toxic if ingested or inhaled. Avoid contact with skin, eyes, or clothing. Wear eye or face protection when handling. If skin or eye contact occurs, wash with copious amounts of water. If ingested or inhaled, contact a physician immediately. Sodium azide yields toxic hydrazoic acid under acidic conditions. Dilute azide-containing compounds in running water before discarding to avoid accumulation of potentially explosive deposits in lead or copper plumbing.

Target
BUB1
(Budding Uninhibited By Benzimidazoles 1 Homolog (Yeast) (BUB1))
Bub1 was initially identified as the mammalian homolog to the yeast protein through a cDNA screen.Bub1 encodes a kinase involved in the formation of the spindle checkpoint, an important mechanism that ensures high fidelity mitotic chromosome segregation.It is thought to be required for assembly of a functional inner centromere, sister chromatid cohesion via targeting of the Shugoshim protein and metaphase congression.Bub1 functions by phosphorylating cdc20, a member of the mitotic checkpoint complex and activating the spindle checkpoint.A related protein kinase Bub3 interacts with Bub1 and targets it to kinetochores prior to chromosome alignment.Mutations in bub1 have been associated with aneuploidy and several forms of cancer.
