Breakthrough study shows how plants sense the world

Plants lack eyes and ears, but they can still see, hear, smell and respond to environmental cues and dangers—especially to virulent pathogens. They do this with the aid of hundreds of membrane proteins that can sense microbes ...

Architecture of mTOR protein complex solved

For a long time it has been known that the protein TOR - Target of Rapamycin - controls cell growth and is involved in the development of diseases such as cancer and diabetes. Researchers at the University of Basel's Biozentrum ...

New technique switches key biomolecules on and off

A new technique that will allow scientists to determine the effects of turning on and off a set of molecules involved in almost every cellular pathway, determine their downstream effects, and uncover new drug targets has ...

Researchers decode targets for hundreds of signaling enzymes

When cells in the human body sense a change in the environment, molecules known as kinases can help them respond: these specialized enzymes activate proteins, propagating signals within a cell that ultimately alter its function. ...

Finding the Achilles' heel of a killer parasite

Two studies led by UT Southwestern researchers shed light on the biology and potential vulnerabilities of schistosomes—parasitic flatworms that cause the little-known tropical disease schistosomiasis. The findings, published ...

How a protein breaks free to cause deadly cancers

Better treatments for some of cancer's deadliest forms could be closer due to a University of California, Irvine-led discovery about how a certain protein is activated in tumor cells. The finding, spearheaded by researchers ...

Protein kinase

A protein kinase is a kinase enzyme that modifies other proteins by chemically adding phosphate groups to them (phosphorylation). Phosphorylation usually results in a functional change of the target protein (substrate) by changing enzyme activity, cellular location, or association with other proteins. The human genome contains about 500 protein kinase genes and they constitute about 2% of all human genes. Protein kinases are also found in bacteria and plants. Up to 30% of all human proteins may be modified by kinase activity, and kinases are known to regulate the majority of cellular pathways, especially those involved in signal transduction.
