Proteins are the infinitely varied chemicals that make cells work, and science has a pretty good idea how they are made. But ...

This article makes a valuable contribution to the field by uncovering a molecular mechanism for miRNA intracellular retention, mediated by the interaction of PCBP2, SYNCRIP, and specific miRNA motifs.

Cornell researchers have found a new and potentially more accurate way to see what proteins are doing inside living cells - using the cells' own components as built-in sensors.
