Cloning, expression and purification of the general stress protein Yhbo from Escherichia coli [PDF]
We cloned, expressed and purified the Escherichia coli yhbO gene product, which is homolog to the Bacillus subtilis general stress protein 18 (the yfkM gene product), the Pyrococcus furiosus intracellular protease PfpI, and the human Parkinson disease protein DJ-1. The gene coding for YhbO was generated by amplifying the yhbO gene from E.

Structural insight into TPX2-stimulated microtubule assembly [PDF]
During mitosis and meiosis, microtubule (MT) assembly is locally upregulated by the chromatin-dependent Ran-GTP pathway. One of its key targets is the MT-associated spindle assembly factor TPX2.

Polymeric Assembly of Gluten Proteins in an Aqueous Ethanol Solvent [PDF]
The supramolecular organization of wheat gluten proteins is largely unknown due to the intrinsic complexity of this family of proteins and their insolubility in water. We fractionate gluten in a water/ethanol (50/50 v/v) and obtain a protein extract which is depleted in gliadin, the monomeric part of wheat gluten proteins, and enriched in glutenin, the

The Cool-2/α-Pix Protein Mediates a Cdc42-Rac Signaling Cascade [PDF]
Background:Cloned-out of library-2 (Cool-2)/PAK-interactive exchange factor (α-Pix) was identified through its ability to bind the Cdc42/Rac target p21-activated kinase (PAK) and has been implicated in certain forms of X-linked mental retardation as well

Mitochondrial dysfunction: Related diseases, influencing factors, and detection
Mitochondrial dysfunction is implicated in the pathogenesis of numerous diseases, including neurological disorders, cancers, and cardiovascular conditions, through mechanisms such as mitochondrial DNA mutations, dysregulation of mitochondrial network dynamics, and impaired mitophagy.

Cellular localization, accumulation and trafficking of double-walled carbon nanotubes in human prostate cancer cells [PDF]
Carbon nanotubes (CNTs) are at present being considered as potential nanovectors with the ability to deliver therapeutic cargoes into living cells. Previous studies established the ability of CNTs to enter cells and their therapeutic utility, but an ...

The Actin‐Binding Prolyl‐Isomerase Par17 Sustains Its Substrate Selectivity by Interdomain Allostery
ABSTRACT The human peptidyl‐prolyl‐cis/trans isomerases (PPIases), Parvulin 14 and Parvulin 17, accelerate the cis/trans isomerization of Xaa‐Pro moieties within protein sequences. By modulating the respective binding interfaces of their target proteins, they play a crucial role in determining the fate of their substrates within the cell. Although both

Delicate Analysis of Interacting Proteins and Their Assemblies by Flow Field-Flow Fractionation Techniques [PDF]
We study the efficiency of several Asymmetrical Flow Field-Flow Fractionation (AF4) techniques to investigate the self-associating wheat gluten proteins. We compare the use of a denaturing buffer including sodium dodecyl sulfate (SDS) and a mild chaotropic solvent, water/ethanol, as eluent, on a model gluten sample.

Structural entanglements in protein complexes [PDF]
We consider multi-chain protein native structures and propose a criterion that determines whether two chains in the system are entangled or not. The criterion is based on the behavior observed by pulling at both temini of each chain simultaneously in the two chains.

Luteinizing hormone receptor knockout mouse: What has it taught us?
Abstract Luteinizing hormone (LH), along with its agonist choriongonadotropin (hCG) in humans, is the key hormone responsible for the tropic regulation of the gonadal function. LH and hCG act through their cognate receptor, the luteinizing hormone/choriongonadotropin receptor (LHCGR; more appropriately LHR in rodents lacking CG), located in the testis ...
