Nucleic acid - protein fingerprints. Novel protein classification based on nucleic acid - protein recognition [PDF]
, 2012 Protein chemistry uses protein description and classification based on molecular mass and isoelectric point as general features. Enzymes are also compared by enzymatic reaction constants, namely Km and kcat values. Proteins are also studied by binding to

RNA‐related functions of BRCA2 in transcription, replication, and genome stability
FEBS Letters, EarlyView.Beyond its role in homologous recombination, BRCA2 regulates R‐loop homeostasis, DNA–RNA hybrid resolution, RNA polymerase II dynamics, and transcriptional activation. Disruption of any of these functions can contribute to genome instability, inflammatory signaling, and tumorigenesis. BRCA2 is a central tumor suppressor protein best known for its roles

Phosphorylation of Adenovirus DNA-binding Protein
Journal of General Virology, 1989 Evidence is presented here which indicates that the adenovirus DNA-binding protein (DBP) is phosphorylated at a tyrosine residue early in infection. This was suggested by the discovery that a proportion of the label in 32P-labelled DBP was resistant to alkali, and was substantiated by acid hydrolysis of DBP immunoprecipitates and by immunoblotting with

Artificial molecular machines and motors—Design and control of nanoscale motion
FEBS Letters, EarlyView.Molecules are constantly moving because of thermal fluctuations, but random motion alone cannot be exploited to perform directional tasks. Artificial molecular machines use chemical, electrical, or light energy to bias this motion. Molecular shuttles, rotary motors, and supramolecular pumps illustrate how nanoscale movement can be controlled and ...

ParB Partition Proteins: Complex Formation and Spreading at Bacterial and Plasmid Centromeres
Frontiers in Molecular Biosciences, 2016 In bacteria, active partition systems contribute to the faithful segregation of both chromosomes and low-copy-number plasmids. Each system depends on a site-specific DNA binding protein to recognize and assemble a partition complex at a centromere-like ...

Grafting Miniature DNA Binding Proteins [PDF]
Chemistry & Biology, 2004 Miniature proteins serve as leads for biological and medicinal applications by positioning all amino acids necessary for biomolecular recognition on a compact protein structure. Protein grafting was recently used to create miniature helical proteins with high DNA binding affinity and specificity.

A context‐dependent modulatory role for eIF6 in acquired resistance to vemurafenib in melanoma
FEBS Letters, EarlyView.Acquired resistance to vemurafenib upregulates the translation factor eIF6 in melanoma cells. Silencing eIF6 in resistant cells reduces proliferation and partially restores drug sensitivity, whereas its overexpression increases sensitivity across melanoma lines regardless of BRAF status, via modulation of mTOR, S6K, and MAPK signaling.

Emerging toolkits for decoding the co-occurrence of modified histones and chromatin proteins
EMBO ReportsIn eukaryotes, DNA is packaged into chromatin with the help of highly conserved histone proteins. Together with DNA-binding proteins, posttranslational modifications (PTMs) on these histones play crucial roles in regulating genome function, cell fate ...
