Building on previous work (Wang et al., 2014), it is shown that the nucleotide exchange factor of the chaperone BiP (Sil1) unexpectedly facilitates the reduction of oxidized BiP.
Sin1, a regulatory subunit of TOR protein kinase, has an evolutionarily conserved domain that specifically binds and recruits substrate for phosphorylation, and may represent a potential target for anti-cancer drugs.
The chaperones Hsp70 and Sis1 collaborate to repress the heat shock response and are both transcriptional targets of the heat shock response, yet only Hsp70 acts as a negative feedback regulator of the heat shock response.
Loss and gain-of-function investigation uncovers a regulatory network controlling human heart chamber specification in which the cardiac precursor gene ISL1 accelerates ventricular induction and antagonizes retinoic acid-driven atrial commitment.
RNA sequencing of the African clawed frog has identified hundreds of putative direct Six1 and Eya1 target genes, including transcriptional regulators of neuronal progenitors and neuronal/sensory differentiation.
The LINE-1 retrotransposon protein, ORF1p, forms a condensate on RNA that is essential for retrotransposition, and may explain cis-preference through a co-translational assembly mechanism.

A comprehensive analysis of the human MICOS complex has identified a novel subunit called QIL1 that is required for cristae junction formation in human cells and Drosophila, through its role in the assembly of the MICOS complex.
Building on previous work (Guarani et al., 2015), MICOS (mitochondrial contact site) assembly and cristae junction formation are shown to have a critical role in human health.
Loading of CD95 and CD95L-derived sequences into the RNA-induced silencing complex elicits a distinct form of RNAi-mediated cell death of cancer cells that results from the targeting of multiple survival genes.
