Cell-based high-throughput screening identifies IBT21 as a chemical chaperone, that inhibits ER protein aggregation and prevents the cell death caused by a proteotoxin, the aggregation-prone prion protein.
The ability of lipid nanodiscs to trap different types of amyloid intermediates, as successfully demonstrated in this study for human-IAPP, could become one of the most powerful approaches to dissect the complicated misfolding pathways of protein aggregation.
The transition to the aggregative stage of Capsaspora owczarzaki, a close unicellular relative to Metazoa, is associated with significant upregulation of orthologs of genes that are important for multicellularity in metazoans.
Contrary to the generally accepted model, condensin maintains proper gene expression by promoting the accurate segregation of chromosomes and the partitioning of the RNA-exosome throughout mitosis, instead of directly regulating transcription.
Formin-2 controls spatiotemporal polymerisation of actin filaments, a common mechanism used by apicomplexans for effective segregation of essential chloroplast-like organelles called apicoplasts, and additionally for daughter formation in Plasmodium falciparum.
Chemical inhibition of Bub1 shows that the catalytic activity is not required for normal mitotic progression, but it makes chromosome segregation and cell proliferation more sensitive to the effects of the anti-cancer drug Paclitaxel.
