WebUpon probing for small RNAs mapping to the MALAT1 locus, we identified a highly conserved 61-nt tRNA-like small RNA (Wilusz et al. 2008). In stark contrast to the mature long MALAT1 transcript, the small RNA is localized exclusively to the cytoplasm, and thus we named it mascRNA, MALAT1-associated small cytoplasmic RNA.
