Fig. 7

Schematic representation of the combinatorial control of Spo11 alternative splicing elicited by RNAPII dynamics and hnRNPH or Sam68 recruitment. At P14, the fast elongation rate of RNAPII promotes recruitment of Sam68 and inclusion of exon 2, thus yielding SPO11β. At P18, reduction of the speed of RNAPII favors recruitment of hnRNPH, which competes out Sam68 and promotes exon 2 skipping and SPO11α splicing.
