Statistics alone are insufficient for study of proteins' signal system Ten years ago great attention was attracted by the discovery that it was possible to demonstrate signal transfer in proteins using statistical methods. In an article in the journal Proceedings of the National Academy of Science (PNAS) Uppsala researchers are now presenting results of experiments that contradict the theory.

Spit tests may soon replace many blood tests One day soon patients may spit in a cup, instead of bracing for a needle prick, when being tested for cancer, heart disease or diabetes. A major step in that direction is the cataloguing of the “complete” salivary proteome, a set of proteins in human ductal saliva, identified by a consortium of three research teams

Longstanding concept of fixed protein structure is challenged by new findings The thousands of proteins found in nature are simply strings of amino acids, assembled by genes, and scientists have long believed that they automatically fold themselves into uniquely fixed, 3-dimensional shapes to fire the engine of life. In the era of genetic research, identifying those shapes and their functions has become a worldwide focus of biomedical science.

Researchers discover how stealthy HIV protein gets into cells Scientists have known for more than a decade that a protein associated with the HIV virus is good at crossing cell membranes, but they didn’t know how it worked. A multidisciplinary team from the University of Illinois has solved the mystery, and their findings could improve the design of therapeutic agents that cross a variety of membrane types.

Spider Silk's strength lies in h-bond cooperation Researchers in Civil and Environmental Engineering at MIT reveal that the strength of a biological material like spider silk lies in the specific geometric configuration of structural proteins, which have small clusters of weak hydrogen bonds that work cooperatively to resist force and dissipate energy.
