Abstract:
Single-stranded DNA binding proteins (SSBs) are critical for binding, protecting and sequestering single-stranded DNA intermediates during multiple cellular transactions, including DNA replication, repair and transcription. The canonical SSB in eukaryotes, Replication Protein A (RPA), is a heterotrimeric protein essential for numerous cellular processes, including DNA repair by homologous recombination (HR). Recently, Richard et al. (2008) identified a novel human SSB, designated human Single-Stranded DNA Binding protein 1 (hSSB1), critical to DNA repair and the maintenance of genomic stabilit

Abstract:
Dda, one of three helicases encoded by bacteriophage T4, has been well- characterized biochemically but its biological role remains unclear. It is thought to be involved in origin-dependent replication, recombination-dependent replication, anti- recombination, recombination repair, as well as in replication fork progression past template-bound nucleosomes and RNA polymerase. One of the proteins that most strongly interacts with Dda, Gp32, is the only single-stranded DNA binding protein (SSB) encoded by T4, is essential for DNA replication, recombination, and repair.

Abstract:
Single stranded DNA (ssDNA) binding proteins (SSBPs), are known key players of DNA damage response (DDR) pathway and play an essential role in stabilising fragile ssDNA generated during DNA replication, transcription and repair. The canonical SSBP is the heterotrimeric Replication Protein A (RPA) which is involved in a number of key cellular processes including replication and repair via Homologous Recombination (HR) in the course of DNA damage. Our lab recently described two new SSBPs, termed SSB1 and SSB2 (also known as NABP2/OBFC2B/SOSS-B1 and NABP1/OBFC2A/SOSSB-2, respectively) which form

Abstract:
The Incil plasmid Colib-P9 was found to carry a single-stranded DNA-binding protein gene (ssb), and the cloned gene was able to suppress the UV and temperature-sensitivity of an ssb-l strain of Escherichia coli K-12. Determination of the nucleotide sequence of Colib ssb demonstrated that the gene shows considerable homology to the ssb gene of plasmid F. In contrast, Southern hybridization techniques indicated that the IncP plasmid RP4 lacks a gene with any extensive homology to F ssb. It was shown that the direction of transfer of Colib-P9 is such that the Colib ssb gene, which lies approximat

Abstract:
Replication protein A (RPA) is a single-stranded DNA-binding protein that is present in all three domains of life. The roles of RPA include stabilising and protecting single- stranded DNA from nuclease degradation during DNA replication and repair. To achieve this, RPA uses an oligosaccharide-binding fold (OB fold) to bind single- stranded DNA. Haloferax volcanii encodes three RPAs – RPA1, RPA2 and RPA3, of which rpa1 and rpa3 are in operons with genes encoding associated proteins (APs). The APs belong to the COG3390 group of proteins found in Euryarchaeota and feature an OB fold. Genetic anal

Abstract:
Single-stranded DNA binding proteins (SSB) bind to single-stranded DNA (ssDNA) that is generated by molecular machines such as helicases and polymerases. SSBs play crucial roles in DNA translation, replication and repair and their importance is demonstrated by their inclusion across all domains of life. The homotetrameric E. coli SSB and the heterotrimeric human RPA demonstrate how SSBs can vary structurally, but all fulfil their roles by employing oligonucleotide/oligosaccharide binding (OB) folds. Nucleofilaments of SSB proteins bound to ssDNA sequester the ssDNA strands, and in doing so pro

Abstract:
Human single-stranded DNA-binding protein 1 (hSSB1) is required for the timely repair of double-strand DNA breaks, as well as the stabilisation and restart of stalled replication forks. In this work, evidence is provided that cellular survival in response to replication stress is promoted by dynamic phosphorylation of hSSB1 by the DNA-dependent protein kinase (DNA-PK) and PPP-family protein phosphatases. These data provide insight into the functional regulation of hSSB1 following replication fork disruption.
