Title: Structural basis for the assembly of the Sxl-Unr translation regulatory complex.
These results suggest that UNR exploits the transcript diversity generated by alternative processing and alternative promoter usage to bind and regulate target genes in a sex-specific manner.
Title: Widespread generation of alternative UTRs contributes to sex-specific RNA binding by UNR.
Efficient msl-2 mRNA silencing via the 3' UTR requires both a poly(A) tail and PABP function, indicating that UNR directly interacts with PABP.
