- Mir-7 microRNA precursor
This family represents the
microRNA (miRNA) precursor mir-7. This miRNA has been predicted or experimentally confirmed in a wide range of species ( [http://microrna.sanger.ac.uk/cgi-bin/sequences/mirna_summary.pl?fam=MIPF0000022 MIPF0000022] ). miRNAs are transcribed as ~70nucleotide precursors (modelled here) and subsequently processed by theDicer enzyme to give a ~22 nucleotide product. In this case the mature sequence comes from the 5' arm of the precursor. The extents of the hairpin precursors are not generally known and are estimated based on hairpin prediction. The products are thought to have regulatory roles through complementarity to mRNA. The involvement of Dicer in miRNA processing suggests a relationship with the phenomenon of RNA interference. miRNAs are numbered based on the sequence of the mature RNA.References
