Single-stranded DNA binding proteins influence APOBEC3A substrate preference

open access: yesScientific Reports, 2021
The cytidine deaminase, APOBEC3A (A3A), is a prominent source of mutations in multiple cancer types. These APOBEC-signature mutations are non-uniformly distributed across cancer genomes, associating with single-stranded (ss) DNA formed during DNA ...

A second DNA binding site on RFC facilitates clamp loading at gapped or nicked DNA

open access: yeseLife, 2022
Clamp loaders place circular sliding clamp proteins onto DNA so that clamp-binding partner proteins can synthesize, scan, and repair the genome. DNA with nicks or small single-stranded gaps are common clamp-loading targets in DNA repair, yet these ...

Non-additivity in protein-DNA binding [PDF]

open access: yesBioinformatics, 2005
Localizing protein binding sites within genomic DNA is of considerable importance, but remains difficult for protein families, such as transcription factors, which have loosely defined target sequences. It is generally assumed that protein affinity for DNA involves additive contributions from successive nucleotide pairs within the target sequence. This

Versatile toolbox for high throughput biochemical and functional studies with fluorescent fusion proteins [PDF]

open access: yes, 2012
Fluorescent fusion proteins are widely used to study protein localization and interaction dynamics in living cells. However, to fully characterize proteins and to understand their function it is crucial to determine biochemical characteristics such as ...

Identification of DNA-binding proteins using support vector machines and evolutionary profiles

open access: yesBMC Bioinformatics, 2007
Background Identification of DNA-binding proteins is one of the major challenges in the field of genome annotation, as these proteins play a crucial role in gene-regulation.

Site-specific DNA Mapping of Protein Binding Orientation Using Azidophenacyl Bromide (APB)

open access: yesBio-Protocol, 2020
The orientation of a DNA-binding protein bound on DNA is determinative in directing the assembly of other associated proteins in the complex for enzymatic action.

Comparative footprinting of DNA-binding proteins [PDF]

open access: yesBioinformatics, 2006
Abstract Motivation: Comparative modelling is a computational method used to tackle a variety of problems in molecular biology and biotechnology. Traditionally it has been applied to model the structure of proteins on their own or bound to small ligands, although more recently it has also been used to model protein-protein interfaces ...

Expression, purification, and solution-state NMR analysis of the two human single-stranded DNA-binding proteins hSSB1 (NABP2/OBFC2B) and hSSB2 (NAPB1/OBFC2A)

open access: yes, 2021
Single-stranded DNA-binding proteins (SSBs) are essential to all living organisms as protectors and guardians of the genome. Apart from the well-characterized RPA, humans have also evolved two further SSBs, termed hSSB1 and hSSB2. Over the last few years,
