- Mir-101 microRNA precursor family
miR-101 microRNA precursor is a small
non-coding RNA that regulatesgene expression . Expression of miR-101 has been validated in both human ( [http://microrna.sanger.ac.uk/cgi-bin/sequences/mirna_entry.pl?acc=MI0000103 MI0000103] , [http://microrna.sanger.ac.uk/cgi-bin/sequences/mirna_entry.pl?acc=MI0000739 MI0000739] ) [cite journal | last = Mourelatos | first = Z | coauthors = Dostie J, Paushkin S, Sharma A, Charroux B, Abel L, Rappsilber J, Mann M, Dreyfuss G | year = 2002 | title = miRNPs: a novel class of ribonucleoproteins containing numerous microRNAs | journal = Genes Dev | volume = 16 | pages = 720–728 | pmid = 11914277 | doi = 10.1101/gad.974702] and mouse ( [http://microrna.sanger.ac.uk/cgi-bin/sequences/mirna_entry.pl?acc=MI0000148 MI0000148] ).

The precursor microRNA is astem-loop structure of about 70nucleotide s in length that is processed by theDicer enzyme to form the 21-24 nucleotide mature microRNA. In this case the mature sequence is excised from the 3' arm of the hairpin.References
