WebNov 21, 2011 · The Cdk1-cyclin A complex regulates late origin firing in S-phase. A constitutively activated Cdk1 allele increases firing of late S-phase origins, whereas a loss of function temperature sensitive allele of Cdk1 has a defect in late origin firing at the restrictive temperature [ 76 ]. 4.2.3. The G2/M transition WebSep 2, 2024 · This autoactivatory mechanism, which depends on ATR and its coactivator ETAA1 and is tightly associated with CHK1 autophosphorylation at S296, counters CHK1 ubiquitylation and proteasomal degradation, thereby preventing attenuation of S-phase checkpoint functions and a compromised capacity to respond to RS.

WebJul 9, 2024 · CHK1 is phosphorylated by ATR at S317 and S345 , and to a lesser extent by ATM on S317 , a prerequisite for autophosphorylation at S296 for full activation of CHK1 (Fig. 1e) . WebAug 31, 2024 · A3A expression caused ATR-dependent phosphorylation of Chk1 and cell-cycle arrest, consistent with replication checkpoint activation. Further, replication checkpoint blockade via small-molecule inhibition of ATR kinase in cells expressing A3A led to apoptosis and cell death.
