A systematic interactome of Saccharomyces cerevisiae SET1C expands its functional landscape and identifies candidate regulatory connections

Set1 is the catalytic subunit of SET1C or COMPASS, which methylates histone H3K4 and serves as a scaffold for the association of seven tightly bound polypeptides. We have employed yeast two-hybrid screenings to determine the interactome of Set1 and each subunit, providing a uniqu...

DNTTIP2 coordinates RNA exosome activities to ensure fidelity of human ribosome assembly

Abstract The RNA exosome-associated helicase Mtr4/MTR4 (yeast/human) is recruited by adaptor proteins bearing Arch-Interacting Motifs (AIMs) to selectively degrade RNA substrates. Although the exosome targets diverse RNAs, only a few adaptors have been identified. Here, we extend...
