چکیده

Misfolding of membrane proteins plays an important role in many human diseases such as retinitis pigmentosa, heredity deafness and diabetes insipidus. Single molecule force spectroscopy is a novel technique which measures the force necessary to pull a protein out of a membrane. Such force distance curves contain valuable information on the proteins structure. High-throughput force spectroscopy experiments generate hundreds of curves. These curves are then evaluated and aligned to generate a two-dimensional plot of unfolding patterns representing the distribution of force and contour length through a Gaussian distribution.

Static magnetic fields modulate X-ray-induced DNA damage in human glioblastoma primary cells

Although static magnetic fields (SMFs) are used extensively in the occupational and medical fields, few comprehensive studies have investigated their possible genotoxic effect and the findings are controversial. With the advent of magnetic resonance imaging-guided radiation therapy, the potential effects of SMFs on ionizing radiation (IR) have become increasingly important. In this study we foc...

Optimizing force spectroscopy by modifying commercial cantilevers: Improved stability, precision, and temporal resolution.

Atomic force microscopy (AFM)-based single-molecule force spectroscopy (SMFS) enables a wide array of studies, from measuring the strength of a ligand-receptor bond to elucidating the complex folding pathway of individual membrane proteins. Such SMFS studies and, more generally, the diverse applications of AFM across biophysics and nanotechnology are improved by enhancing data quality via impro...

Arabidopsis leaf plasma membrane proteome using a gel free method: Focus on receptor–like kinases

The hydrophobic proteins of plant plasma membrane still remain largely unknown.  For example in the Arabidopsis genome, receptor-like kinases (RLKs) are plasma membrane proteins, functioning as the primary receptors in the signaling of stress conditions, hormones and the presence of pathogens form a diverse family of over 610 genes. A limited number of these proteins have appeard in pr...

High-resolution atomic force microscopy and spectroscopy of native membrane proteins

Membranes confining cells and cellular compartments are essential for life. Membrane proteins are molecular machines that equip cell membranes with highly sophisticated functionality. Examples of such functions are signaling, ion pumping, energy conversion, molecular transport, specific ligand binding, cell adhesion and protein trafficking. However, it is not well understood how most membrane p...
