Phosphatase in dna replication
WebAug 14, 2013 · Once the potent dNTP triphophohydrolase activity of SAMHD1 is removed, the virus polymerase can replicate the virus genome. Thus, DNA viruses, such as herpes simplex virus type 1 and vaccinia virus, which encode their own DNA polymerases, can replicate in noncycling cells if SAMHD1 is removed . WebOct 1, 2024 · Although not fully understood, phosphatases have been shown to regulate multiple aspects of replication initiation. Many kinases involved in DNA replication control, such as ATR-Chk1 are important targets for the generation of new chemotherapies [155].
