When exposed to stress, bacteria allow their metabolism to take a break during which they suppress, for example, the incorporation of proteins into membranes. Scientists from Marburg, Freiburg and Munich have discovered this ...

Most organisms have proteins that react to light. Even creatures that don't have eyes or other visual organs use these proteins to regulate many cellular processes, such as transcription, translation, cell growth and cell ...

Specific nuclear proteins act as a glue to pack genetic material in an absurdly small space in the human body. Proteins "gluing" DNA are called linker histones, and hold their secret in their electric charge. They are strongly ...

Fluorescence light microscopy has the unique ability to observe cellular processes over a scale that bridges four orders of magnitude. Yet, its application to living cells is fundamentally limited by the very rapid and unceasing ...

By combining two microscopy methods, EPFL researchers are able to see what is happening inside a cell and on its membrane simultaneously, giving unprecedented insight into the cellular processes that occur during infection, ...

Cellular processes on membranes are often fast and short-lived. Molecules assemble briefly, separate again, interact with different partners and move along or through the membrane. It is therefore important to not only study ...

Cellular processes are regulated through the balance between protein shapes that confer active or inactive functions. In the complexity of cellular regulations, the preferred shape (or conformation) of a protein often depends ...

A phenomenon in which an RNA named NORAD drives a protein named Pumilio to form liquid droplets in cells, much like oil in water, appears to tightly regulate the activity of Pumilio. A new study led by UT Southwestern scientists ...

Our proteome is much bigger than our genome because one gene produces several variants of proteins called protein isoforms, whose disbalance is implicated in many diseases. A new bioengineered reporter system developed at ...
