A new player in the innate immunity game?

Scientists have demonstrated for the first time that a certain class of RNA (known as long non-protein-coding RNA [lncRNA]) are involved in the host response to viral infection. These findings, published today in the online journal mBio®, could gr…

Molecular machine shuffles beads on a DNA string

Yards of DNA are packed into cells by wrapping the DNA around proteins called nucleosomes. But that tight packing makes it hard for the cell’s machinery to get at the DNA code to read, copy or repair it. Now researchers at the University of California, Davis, have shown how two proteins form a molecular machine that shuffles the nucleosomes out of the way to expose the DNA double helix.
