Volume 32, Issue 5

On the cover: The high-density genetic interaction map of factors involved in RNA processing described in this issue begins to untangle a complex network of functional relationships. As described by Wilmes et al. (p. 735) and also in the accompanying manuscript by Kress et al. (p. 727), this genetic interaction map aided in the elucidation of additional functions for previously described factors and also suggests roles for previously uncharacterized factors. Furthermore, as represented by the bird and serpent emerging from the tapestry depicted in the cover image, systems-level analysis of the data set gives rise to some insight into the global interactions among complexes and pathways that contribute to the dynamic cycle of creation and destruction of RNA molecules within the cell.

CDYL bridges G9a and REST
Tumorigenesis is caused by activation of oncogenes and inactivation of tumor suppressor genes. Mulligan et al. report that CDYL bridges the histone methyltransferase G9a and the tumor suppressor REST to repress transcription and cellular transformation.
Npl3 promotes pre-mRNA splicing
SR proteins play key roles in pre-mRNA splicing in mammals. Kress et al. demonstrate that a yeast SR-like protein, Npl3, affects splicing of many pre-mRNAs by a mechanism involving co-transcriptional recruitment of splicing factors to chromatin.
Genetic interaction map of RNA processing factors
All functional RNAs undergo a series of maturation events collectively termed RNA processing. Wilmes et al. report a high-density genetic interaction map of RNA processing factors that revealed many functional connections, including links between the splicing and export machineries and the proteasome component Sem1/Dss1.

The Control of mRNA Decapping and P-Body Formation
Tobias M. Franks and Jens Lykke-Andersen

mRNA regulation is critical for proper gene expression, and cells utilize many pathways to achieve such control. In this Review, Toby Franks and Jens Lykke-Anderson describe a kinetic model for how translational repression, mRNP multimerization, and mRNA decay direct mRNP assembly into P bodies.

Featured Topic

Coregulators of transcription, coactivators and corepressors, are often found in multiprotein complexes that assist in the communication between transcription factors and RNA polymerase II. The following selection of articles and FREE Reviews samples some of the interesting mechanisms by which coregulators work to regulate the activities of sequence-specific transcription factors.
