snRNAmiRNA
snRNAmiRNA refers to small RNA species that originate from small nuclear RNAs (snRNAs) and exhibit microRNA-like regulatory activity. They are a subclass of small RNAs that resemble miRNAs in size (roughly 21–24 nucleotides) and association with Argonaute proteins, and capable of guiding RNA-induced silencing complexes to target mRNAs to repress translation or promote degradation. They have been reported in multiple species, including humans and other vertebrates, with additional identification in plants.
snRNA genes are transcribed as part of the snRNP biogenesis pathway. Some snRNAmiRNAs are generated from snRNA
Like canonical miRNAs, snRNAmiRNAs are thought to regulate gene expression post-transcriptionally by base-pairing with complementary sequences
Because snRNA genes often reside in distinct genomic contexts and produce snRNA fragments through nucleolytic processing,
