RNPs assembled on POLIII-derived ncRNA and their functions. NcRNAs act in concert with RBPs to exert a variety of cellular functions. POLIII-derived ncRNAs can either act as scaffolds (e.g. 7SL and Y3**) or as decoys (e.g. 7SK and Y3). The function of other ncRNA scaffold is not outlined here (e.g. 5S or U6). Note that although some POLIII-derived ncRNAs were identified long ago, a precise molecular role was not yet identified (e.g. vtRNAs and snaRs).
