Spliceosomal helicases DDX41/SACY-1 and PRP22/MOG-5 both contribute to proofreading against proximal 3' splice site usage
Alleles of C. elegans genes mog-5 and sacy-1 were found to increase usage of proximal 3' splice sites Overall design: Alternate splicing analysis of sacy-1(tn1385) vs N2(wildtype) and mog-5(az192) vs N2
