Table 1 List of helper and recipient hairpins that exist in clustered orientation, as shown in this review
From: MicroRNA clustering on the biogenesis of suboptimal microRNAs
| Â | Helper hairpin | Recipient hairpin | Cluster assistance | References |
|---|---|---|---|---|
1 | miR-11 | miR-998 | Presence of miR-11 increases the expression level of miR-98 | [20] |
2 | miR-BHRF1-2 | miR-BHRF1-3 | Cluster assistance is valid in certain viral miRNA clusters as well. miR-BHRF1-2 benefits the processing of miR-BHRF1-3 | [24] |
3 | miR-195a | miR-497a | Presence of miR-195a increases the expression level of miR-497a | [27] |
4 | miR-144 | miR-451 | Expression of miR-451, the most abundant miRNA in erythrocytes, is highly dependent on miR-144 | [13] |
5 | miR-16-1 | miR-15a | miR-16-1 benefits the processing of neighboring miR-15a | [19] |
