In a paper published online in advance in Nucleic Acids Research this week, investigators at Sloan-Kettering and Weill Cornell Medical College show that the activity of Nam8, a yeast U1 snRNP component that "collaborates with Mer1 to promote splicing of essential meiotic mRNAs," is weakened by "mutations in the putative RNA binding site of the RRM2 and RRM3 domains." More specifically, the team says SPO22 and PCH2 are targets of Nam8-dependent meiotic splicing; the researchers als
