Phosphorylation of human replication protein A by the DNA-dependent protein kinase is involved in the modulation of DNA replication.
The single-stranded DNA-binding protein, Replication Protein A (RPA), is a heterotrimeric complex with subunits of 70, 32 and 14 kDa involved in DNA metabolism. RPA may be a target for cellular regulation; the 32 kDa subunit (RPA32) is phosphorylated by several cellular kinases including the DNA-dependent protein kinase (DNA-PK). We have purified a mutant hRPA complex lacking amino acids 1-33 o...
متن کاملc-myc protein can be substituted for SV40 T antigen in SV40 DNA replication.
Replicating activity of SV40 origin-containing plasmid was tested in human cells as well as in monkey CosI cells. All the plasmids possessing SV40 ori sequences could replicate, even in the absence of SV40 T antigen, in human HL-60 and Raji cells which are expressing c-myc gene at high level. The copy numbers of the replicated plasmids in these human cells were 1/100 as high as in monkey CosI c...
متن کاملReplication protein A in Pyrococcus furiosus is involved in homologous DNA recombination.
Single-stranded DNA-binding protein in Bacteria and replication protein A (RPA) in Eukarya play crucial roles in DNA replication, repair, and recombination processes. We identified an RPA complex from the hyperthermophilic archaeon, Pyrococcus furiosus. Unlike the single-peptide RPAs from the methanogenic archaea, Methanococcus jannaschii and Methanothermobacter thermoautotrophicus, P. furiosus...
متن کاملDrosophila RecQ4 Is Directly Involved in Both DNA Replication and the Response to UV Damage in S2 Cells
The RecQ4 protein shows homology to both the S.cerevisiae DNA replication protein Sld2 and the DNA repair related RecQ helicases. Experimental data also suggest replication and repair functions for RecQ4, but the precise details of its involvement remain to be clarified.Here we show that depletion of DmRecQ4 by dsRNA interference in S2 cells causes defects consistent with a replication function...
متن کاملABAP1 is a novel plant Armadillo BTB protein involved in DNA replication and transcription.
In multicellular organisms, organogenesis requires a tight control of the balance between cell division and cell differentiation. Distinct signalling pathways that connect both cellular processes with developmental cues might have evolved to suit different developmental plans. Here, we identified and characterized a novel protein that interacts with pre-replication complex (pre-RC) subunits, de...
