Table 2

Vertebrate microRNA clusters. The table lists the maximal number of microRNAs in a single copy of the cluster ("Members"), the maximal number of non-homologous microRNAs in a single copy ("Families"), and the maximal number of paralogous cluster copies in any of the investigated genomes.

* part of the human mir-134 cluster experimentally investigated in [33]. In the same study it is reported that mir-144 and mir-224 are also parts of clusters with additional microRNAs that do not have orthologs in the MR 6.0.
