Functional domains of the influenza A virus PB2 protein:identification of NP- and PB1-binding sites [PDF]

open access: yes, 2004
Influenza virus genomic RNA segments are packaged into ribonucleoprotein (RNP) structures by the PB1, PB2, and PA subunits of an RNA polymerase and a single-strand RNA-binding nucleoprotein (NP).

Mapping of the ligand-binding site on the b ' domain of human PDI: interaction with peptide ligands and the x-linker region [PDF]

open access: yes, 2009
PDI (protein disulfide-isomerase) catalyses the formation of native disulfide bonds of secretory proteins in the endoplasmic reticulum. PDI consists of four thioredoxin-like domains, of which two contain redox-active catalytic sites (a and a'), and two ...

Charge environments around phosphorylation sites in proteins [PDF]

open access: yes, 2008
Background: Phosphorylation is a central feature in many biological processes. Structural analyses have identified the importance of charge-charge interactions, for example mediating phosphorylation-driven allosteric change and protein binding to ...

Diversity of molecular targets and signaling pathways for CBD

open access: yesPharmacology Research & Perspectives, 2020
Cannabidiol (CBD) is the second most abundant component of the Cannabis plant and is known to have effects distinct from Δ9‐tetrahydrocannabinol (THC). Many studies that examined the behavioral effects of CBD concluded that it lacks the psychotomimetic ...

Identification of hACE2-interacting sites in SARS-CoV-2 spike receptor binding domain for antiviral drugs screening

open access: yesVirus Research, 2022
The key structure of the interface between the spike protein of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) and human angiotensin-converting enzyme 2 (hACE2) acts as an essential switch for cell entry by the virus and drugs targets ...

The Chromosomal High-Affinity Binding Sites for the Drosophila Dosage Compensation Complex [PDF]

open access: yes, 2008
Dosage compensation in male Drosophila relies on the X chromosome-specific recruitment of a chromatin-modifying machinery, the dosage compensation complex (DCC). The principles that assure selective targeting of the DCC are unknown.

Data of protein-RNA binding sites

open access: yesData in Brief, 2017
Despite the increasing number of protein-RNA complexes in structure databases, few data resources have been made available which can be readily used in developing or testing a method for predicting either protein-binding sites in RNA sequences or RNA ...

Metal-ion binding and metal-ion induced folding of the adenine-sensing riboswitch aptamer domain [PDF]

open access: yes, 2010
Divalent cations are important in the folding and stabilization of complex RNA structures. The adenine-sensing riboswitch controls the expression of mRNAs for proteins involved in purine metabolism by directly sensing intracellular adenine levels ...

A novel prediction method for protein DNA-binding residues based on neighboring residue correlations

open access: yesBiotechnology & Biotechnological Equipment, 2022
Accurately identifying the protein DNA-binding residues is important for understanding the protein–DNA recognition mechanism and protein function annotation.

Turnover and function of DNA methylation at transcription factor binding sites [PDF]

open access: yes, 2014
Cell type identity is largely determined by regulatory networks consistent of various transcription factors. Transcription factor activity requires interaction with DNA and thus critically depends on the accessibility of binding motifs.
