Researchers at the Hebrew University of Jerusalem have succeeded in discovering and isolating a new protein from the poplar tree with special structural and qualitative characteristics that could have consequences for development of future nanocapsules for drug delivery to cancer cells.
"Bagel-shaped" SP-1 protein
In addition to being obtained from plant tissue, the protein can now also be produced in large quantities as a recombinant protein in bacteria, making it highly available for medicinal or other applications.
Called SP-1, the protein has a nanometric, “bagel-shaped,” circular form and is extremely stable. It has been found to be capable of surviving contact with enzymes that break down proteins or exposure to extreme conditions such as boiling, excessive acidity, salinity, organic solvents or detergent solutions.

Researchers from TU Graz and their industry partners have unveiled a world first: the prototype of a robot-controlled, high-speed combined charging system (CCS) for electric vehicles that enables series charging of cars in various parking positions.
Global demand for electric vehicles is forecast to rise sharply: by 2025, the number of new vehicle registrations is expected to reach 25 million per year....
Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.
Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...
