Arabidopsis TITAN-LIKE is required for U12-type intron splicing, especially of AT-AC subtypes.

Many eukaryotes possess two types of spliceosomes: the U2-dependent and U12-dependent spliceosomes. The U2-dependent spliceosome processes >99% of all introns, whereas the U12-dependent spliceosome acts on only ~0.3% of introns, one-third of which start with AT and end with AC, w...
