Small temporal RNA

Small temporal RNA (abbreviated stRNA) regulates gene expression during roundworm development by preventing the mRNAs they bind from being translated.[1] In contrast to siRNA, stRNAs downregulate expression of target RNAs after translation initiation without affecting mRNA stability.[2] Nowadays, stRNAs are better known as miRNAs.

stRNAs exert negative post-transcriptional regulation by binding to complementary sequences in the 3' untranslated regions of their target genes. stRNAs are transcribed as longer precursor RNAs that are processed by the RNase
