TL;DR: The large range of protein expression levels limits the ability of the 2DE-MS approach to analyze proteins of medium to low abundance, and thus the potential of this technique for proteome analysis is likewise limited.

TL;DR: The purification of an RNAi effector complex termed RITS (RNA-induced initiation of transcriptional gene silencing) that is required for heterochromatin assembly in fission yeast is described and a mechanism for the role of the RNAi machinery and small RNAs in targeting of heterochROMatin complexes and epigenetic genesilencing at specific chromosomal loci is suggested.

TL;DR: 4E-BP1 phosphorylation by FRAP/mTOR on Thr-37 and Thr-46 is a priming event for subsequent phosphorylated of the carboxy-terminal serum-sensitive sites, including those that interact with eIF4E.

TL;DR: Using high-throughput affinity-purification mass spectrometry, BioPlex is used to identify interacting partners for 2,594 human proteins in HEK293T cells and reveals associations among thousands of protein domains, suggesting a basis for examining structurally related proteins.

TL;DR: With more than 56,000 candidate interactions, BioPlex 2.0 exceeds previous experimentally derived interaction networks in depth and breadth, and will be a valuable resource for exploring the biology of incompletely characterized proteins and for elucidating larger-scale patterns of proteome organization.
