RNA-binding proteins (RBPs) determine the stability and hence the function of mRNAs, and thus control the translation of genetic information into proteins. They therefore play vital roles in the differentiation, function – and pathological malfunctions – of immune cells. The complete set of RBPs expressed in T-cells (the ‘RBPome’) has now been identified.

The data show that the regulation of mRNAs by known RBPs is modulated by positive and negative interactions with other RBPs. Surprisingly, this suggests the existence of cell-type-specific regulatory networks.
