Example sentences for: impinge
How can you use “impinge” in a sentence? Here are some example sentences to help you improve your vocabulary:
First, PTEN's protein phosphatase activity is able to down-regulate focal adhesion kinase (FAK) phosphorylation, which leads to the inactivation of the Ras/MAP kinase pathway [ 19 20 21 ] . Second, its lipid phosphatase activity targets the second messenger phosphatidylinositol 3,4,5-trisphosphate [PtdIns(3,4,5)P 3 ] and thereby blocks activation of the protein kinase B (PKB/Akt) pathway [ 11 18 22 23 24 ] . Whereas both of the above pathways are intimately involved in the control of cell growth and survival, PTEN-regulated FAK activity further appears to impinge on cell adhesion, cell migration, and cell invasion [ 20 21 ] . It therefore emerges that the loss of PTEN activity may confer increased survival ability, proliferative potential, and invasive capacity on cells, and thereby may promote progression towards a more malignant phenotype.
Cdc5 is required for full activation of the Dbf2-Mob1 protein kinase complex [ 15 16 17 ] , and has been proposed to impinge on the MEN both upstream and downstream of Tem1 [ 15 16 17 18 ] . During exit from mitosis, Cdc5 is required for Clb2 destruction, and similar to over-expression of Cdc14 [ 3 ] , induction of Cdc5 triggers precocious Clb2 degradation in pre-anaphase cells [ 19 20 ] . In addition to its role in exit from mitosis, Cdc5 has other functions during mitosis in budding yeast.
Although some donkey carts and bicycles occasionally impinge on the tranquillity of the main street, the townsfolk have plenty of time to stand around and gossip.
Markets operate on felt signals, and it is taking too long for the signal that there is an excess of doctors (especially very high-priced specialists) to impinge upon the supply-producing parts of the system.
Biochemical and cell biological experiments indicate that Net1 acts as part of a complex named RENT that tethers Cdc14 to the nucleolus and inhibits Cdc14 phosphatase activity, and that CDC15 and TEM1 are required for the release of Cdc14 from Net1 at the end of mitosis [ 15 16 17 43 ] . Consistent with this notion, both net1 tab 2-1(which encodes a mutant version of Net1 with presumably reduced affinity for Cdc14) and CDC14 TAB 6-1(which encodes a mutant version of Cdc14 with reduced affinity for Tab2/Net1) bypass cdc15Δ [ 15 18 ] . Both net1 tab 2-1and CDC14 TAB 6-1impinge directly on mitotic exit, suggesting that other TAB genes may encode physiological regulators and effectors of the Mitotic Exit Network.
