> determinant of whether an intron would be spliced out of the mRNA transcript.

I thought introns were virtually always spliced out of the MRNA transcript ... is this study saying that's not true?

This is about a protein family that mediate different classes of splice sites.

If you're interested in the larger context you might look into the term "alternative splicing" to learn more.
