WebInterestingly, eIF4E-sensitive SFs include U2 snRNP components SF3B1 and U2AF1, which function in splice-site selection. Indeed, these SFs can be present in sub-stoichiometric quantities relative to the enzymatic machinery of the spliceosome (Wahl et al , 2009 ), and thus, their modulation by eIF4E likely provides a means to shift splice-site preferences. WebFirst is a target-gene binding domain that can be tailored to any gene. The second domain inhibits mRNA maturation by binding U1 snRNP, a component of the cellular splicing apparatus. By combining both capabilities in the same molecule, the U1 Adaptor can inhibit the pre-mRNA maturation step of polyA tail addition in a gene specific manner.
