U12-dependent (U12) introns have persisted in the genomes of plants since the ancestral divergence between plants and metazoans. These introns, which are rare, are found in a range of genes that include essential functions in DNA replication and RNA metabolism and are implicated in regulating the expression of their host genes. U12 introns are removed from pre-mRNAs by a U12 intron-specific spliceosome. Although this spliceosome shares many properties with the more abundant U2-dependent (U2… CONTINUE READING
