A small intron of Drosophila gamma carboxylase, not predictable in silico for mammalian splicing machinery, is spliced improperly in human cells

The splicing of two small introns of 58 and 67 nucleotides (nts) of the Drosophila gamma carboxylase (DγC) in cultured human cells was examined. The two introns are below the minimum size, which was proposed as a requirement for an intron to be spliced in human cells.
