Study identifies strategy to avoid resistance to cancer therapy

Resistance to therapies is one of the obstacles to overcome in cancer treatments. Understanding the mechanisms of this resistance is essential to design strategies that favor tumor cell death. A study led by the Protein Kinases ...

New clues to the mechanism behind treatment-resistant depression

Major depressive disorder (MDD) is a widespread mental health condition that for many is disabling. It has long been appreciated that MDD has genetic as well as environmental influences. In a new study in Biological Psychiatry ...

Repurposed drug shows promise for treating cardiac arrhythmias

Ruxolitinib, a drug that is already approved by the U.S. Food and Drug Administration (FDA) for treating certain cancers and skin conditions, is effective at inhibiting CaMKII, a protein kinase linked to cardiac arrhythmias.

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.
