Molecular biologists compared human and yeast FACT

A protein complex called facilitates chromatin transcription (FACT) plays a role in DNA packing within a nucleus, as well as in oncogenesis. A team of scientists from MSU, working in cooperation with foreign colleagues, have ...

How a cell knows when to divide

How does a cell know when to divide? We know that hundreds of genes contribute to a wave of activity linked to cell division, but to generate that wave new research shows that cells must first grow large enough to produce ...

A brewer's tale of proteins and beer

The transformation of barley grains into beer is an old story, typically starring water, yeast and hops. Now, in a report in the Journal of Proteome Research, scientists are highlighting another character in this tale: proteins. ...

Sticking sugar to protein

ETH researchers have succeeded in determining the 3-D structure of the enzyme that attaches sugar chains to proteins – a breakthrough that they recently published in the journal Science.

Islands in yeast membrane revealed by extreme microscopy

University of Groningen microbiologists have visualized tiny islands in the cell membrane of baker's yeast. These membrane compartments appear to store transport proteins before use. The scientists observed that these proteins ...

Fruit fly hunger games—taste neurons in control

A team of neuroscientists from the Champalimaud Centre for the Unknown (CCU), in Lisbon, Portugal, has discovered that specific taste neurons located in the fruit fly's proboscis confer a craving for protein. The results, ...

The birth of a new protein

A yeast protein that evolved from scratch can fold into a three-dimensional shape—contrary to the general understanding of young proteins—according to new research led by the University of Arizona.
