01 Sequence and arms

The mature, its arm and its hairpin

hsa-miR-216b-3p is 22 nt, the 3p arm of the 82 nt hairpin hsa-mir-216b; the other arm is hsa-miR-216b-5p. Its sequence changed in miRBase release 23.

What this tells you

miRBase's files name this mature, its accession, its sequence and the hairpin it derives from, and the GFF3 places both on the genome. Of the hairpins the GFF3's header says: “Note, these sequences do not represent the full primary transcript, rather a predicted stem-loop portion that includes the precursor miRNA.”

A sentence from RefSeq's summary on the gene, as NCBI Gene carries it: “The primary transcript is cleaved by the Drosha ribonuclease III enzyme to produce an approximately 70-nt stem-loop precursor miRNA (pre-miRNA), which is further cleaved by the cytoplasmic Dicer ribonuclease to generate the mature miRNA and antisense miRNA star (miRNA*) products.” [RefSeq, Sep 2009].

The arm suffix is miRBase's naming. The README of release 23 says: “20514 mature sequences have had their names clarified, usually upon the addition of a 2nd mature product from the same locus. For example, hsa-miR-107 is renamed to hsa-miR-107-3p on the addition of hsa-miR-107-5p to the database.” The convention that mir names a hairpin and miR a mature is the annotation guidelines paper the README cites: Ambros V, Bartel B, Bartel DP, Burge CB, Carrington JC, Chen X, Dreyfuss G, Eddy SR, Griffiths-Jones S, Marshall M, Matzke M, Ruvkun G, Tuschl T. A uniform system for microRNA annotation. RNA 2003 9(3):277-279. PubMed 12592000, DOI 10.1261/rna.2183803. miRBase itself is cited as the credit line carries it: Kozomara A, Birgaoanu M, Griffiths-Jones S. miRBase: from microRNA sequences to function. Nucleic Acids Res 2019 47(D1):D155-D162. PubMed 30423142, DOI 10.1093/nar/gky1141.

The seed drawn on the mature is a cited definition, not a measurement. MirGeneDB's information page (read 2026-09-08) says: “Nucleotide positions 2 through 8 of the mature sequence (the "seed") are strongly conserved through evolution, as are positions 13-16 (the 3' complementary region) (13,20,21).” TargetScan's FAQ defines its site types by the same positions counted two ways: “7mer-m8: An exact match to positions 2-8 of the mature miRNA (the seed + position 8)” and “7mer-1A: An exact match to positions 2-7 of the mature miRNA” followed by an A. So TargetScan's seed proper is positions 2 to 7, and the span this page shades, 2 to 8, is MirGeneDB's.

The two arms are different microRNAs, so an antagomir or a mimic is made against one of them; the other arm has its own page, and the order door of this page carries this arm's name.

What this tells you

The hairpin is a gene to the nomenclature authorities and to NCBI Gene and Ensembl: HGNC for human, MGI for mouse and RGD for rat name it, NCBI places it on the reference annotation and RefSeq holds its stem-loop record, and Ensembl places it and says what other gene its span lies inside. Each placement is on the assembly its source names, and the card never converts one into another.

A sentence from RefSeq's summary on the gene, as NCBI Gene carries it: “miRNAs are transcribed by RNA polymerase II as part of capped and polyadenylated primary transcripts (pri-miRNAs) that can be either protein-coding or non-coding.” [RefSeq, Sep 2009].

The gene page holds the locus's own records: the transcripts, the variants and the disease associations are the gene's, and this card links to it rather than repeating them as if they were this arm's.

RefSeq's summary on the gene MIR216B, as NCBI Gene carries it, quoted as written.

microRNAs (miRNAs) are short (20-24 nt) non-coding RNAs that are involved in post-transcriptional regulation of gene expression in multicellular organisms by affecting both the stability and translation of mRNAs. miRNAs are transcribed by RNA polymerase II as part of capped and polyadenylated primary transcripts (pri-miRNAs) that can be either protein-coding or non-coding. The primary transcript is cleaved by the Drosha ribonuclease III enzyme to produce an approximately 70-nt stem-loop precursor miRNA (pre-miRNA), which is further cleaved by the cytoplasmic Dicer ribonuclease to generate the mature miRNA and antisense miRNA star (miRNA*) products. The mature miRNA is incorporated into a RNA-induced silencing complex (RISC), which recognizes target mRNAs through imperfect base pairing with the miRNA and most commonly results in translational inhibition or destabilization of the target mRNA. The RefSeq represents the predicted microRNA stem-loop.

09 Inhibit or mimic this microRNA

Targeting hsa-miR-216b-3p

The order page opens with hsa-miR-216b-3p and human filled in, with AUMantagomir sdASO and AUMmimic sdASO side by side and the price on that page. Five decisions are yours before it does. What is written under each is AUM's guidance; the timings and the concentrations are in the usage guide below.

01
Choose the arm
The mature named on this page is one arm of its hairpin; the other arm, hsa-miR-216b-5p, is a different microRNA with its own page. An inhibitor or a mimic is made against one arm, and the order door of this page carries hsa-miR-216b-3p.
02
Inhibit or replace
An AUMantagomir sdASO inhibits the mature microRNA; an AUMmimic sdASO supplies one. Both are self-delivering. AUMantagomir toASO is the transfection-optimised version of AUMantagomir sdASO, a lower-cost option that needs a transfection reagent.
03
Check the species
The sequence is human's, as miRBase release 23 writes it. Where the orthologs card shows the same arm in another species with another sequence, a design for one species is not a design for the other; where the bases are the same, that is a sequence fact the card states, not a claim about the two.
04
Run the controls
A scramble control of the same chemistry, the positive control the order page offers for the product, untreated cells, and a mock condition wherever a transfection reagent is used. The order page lists the controls beside the product.
05
Read the result at the target level
Inhibiting or supplying a microRNA is read in what it acts on, not in the microRNA alone: the transcripts and the proteins your own experiment names as its targets. The usage guide gives the timing and the concentrations to start from; nothing on this page names a target.
