We have developed a protocol for identifying proteins that are predisposed to bind linear epitopes on target proteins of interest. The protocol searches through the protein database for proteins (scaffolds) that are bound to peptides with sequences similar to accessible, linear epitopes on the target protein. The sequence match is considered more significant if residues calculated to be importa...

Abstract Synthetic binding proteins that have the ability to bind with molecules can be generated using various protein domains as non-antibody scaffolds. These designer been used widely in research studies, their properties overcome disadvantages of antibodies. Here, we describe first application a phage display generate synthetic sweet protein, monellin, scaffold. Single-chain monellin (scMon...

The feasibility of bone transport with bone substitute and the factors which are essential for a successful bone transport are unknown. We studied six groups of 12 Japanese white rabbits. Groups A to D received cylindrical autologous bone segments and groups E and F hydroxyapatite prostheses. The periosteum was preserved in group A so that its segments had a blood supply, cells, proteins and sc...

Several neurodegenerative disorders, including Parkinson's and Alzheimer's diseases, are characterized neuropathologically by accumulation of misfolded proteins such as alpha-synuclein that disrupts scaffold molecules in the caveolae. A new study by Ihara et al. in this issue of Neuron shows that a novel scaffold protein, Sept4, may be an important player in modulating the pathological alterati...

Scaffold proteins play an important role in coordinating signal transduction cascades. However, their exact mechanism of action and the ultimate effect they have on the signal output remain unclear. Ferrell discusses how computer simulations have provided insight into the multiple possible functions that scaffold proteins may have. What remains is to test the predictions in real cells to determ...

The components of MAPK (mitogen-activated protein kinase) signalling pathways can assemble into complexes that are co-ordinated by regulatory proteins including scaffold proteins. There is increasing evidence that scaffold proteins (i) maintain signalling specificity and facilitate the activation of pathway components, (ii) localize pathway components to particular subcellular sites or to speci...

Cells coordinate and integrate various functional modules that control their dynamics, intracellular trafficking, metabolism and gene expression. Such capacity is mediated by specific scaffold proteins that tether multiple components of signaling pathways at plasma membrane, Golgi apparatus, mitochondria, endoplasmic reticulum, nucleus and in more specialized subcellular structures such as foca...

Human apolipoprotein A-1 (apo A-1) is the major protein component of high-density lipoproteins. The apo A-1 lipid-binding domain was used as a template for the synthesis of amphipathic helical proteins termed membrane scaffold proteins, employed to self-assemble soluble monodisperse discoidal particles called Nanodiscs. In these particles, membrane scaffold proteins surround a lipid bilayer in ...

peripheral nerve injuries caused by traffic accidents, resections of tumors or iatrogenic side effects of the surgeries are few of the most common form of trauma occurring with up to 500,000 cases each year in iran. conventional strategies including nerve coaptation, and the application of autografts, allografts and xenografts are restricted due to the limited availability of donors, immune-rej...
