Example sentences for: bub
How can you use “bub” in a sentence? Here are some example sentences to help you improve your vocabulary:
The Bub2/Bfa1 GTPase-activating protein (GAP) complex inhibits the MEN and cytokinesis in response to DNA damage and spindle misorientation ( [ 32 ] ; reviewed in [ 33 ] ). bub2Δ and CDC14 TAB 6-1cells show similar chromosome instability as wild-type cells.
Because the putative Tem1 antagonists and mitotic checkpoint proteins Bub2 and Bfa1 negatively regulate exit from mitosis and cytokinesis in response to both DNA damage and spindle misorientation ( [ 32 ] ; reviewed in [ 33 ] ), we asked whether bypass of TEM1 -dependent regulation can cause chromosome instability.
Consistent with this notion, cells lacking Bub2 (an inhibitor of Tem1) showed a similarly moderate extent of chromosome loss (5%) (Figure 5).
Cdc5 presumably impinges on the MEN by other means as well, because Cdc5 is required for maximal Dbf2 protein kinase activity even in the absence of Bfa1's obligate partner Bub2 [ 18 ] . Once activated, the MEN in turn sustains the transient Cdc14 release enabled by Cdc5 and other FEAR pathway components.
When cells were pre-grown in YPD liquid (instead of SD-URA solid) media before being tested on YPD plates, the percentage of colonies that were red or had red sectors remained similar for wild-type, CDC14 TAB 6-1 , and bub2Δ strains, but was ~25% for net1 tab 2-1.
