Building on previous work (Ge et al., 2013), it is shown that the ER-Golgi intermediate compartment is a platform for the production of COPII vesicles as precursor membranes for the lipidation of LC3, which is an essential step in autophagosome biogenesis.
Parallel horizontal gene transfer has spread a bacteriolytic gene family to all domains of life, and has bestowed a niche-transcending adaptation in recipients that must deploy antibacterial molecules to survive in a bacterial world.
In Drosophila melanogaster, nutrition controls body size by acting through the Forkhead Box class O (FoxO)/Ultraspiracle complex to regulate nutrition-sensitive ecdysone biosynthesis, thereby controlling the switch to stop growth.
Building on previous work (Meigh et al., 2013) we show that A88V, a mutation in connexin26 (Cx26) that causes Keratitis-Ichthyosis-Deafness (KID) syndrome in humans, is linked to a lack of sensitivity to CO2 by Cx26 hemichannels.
Ectopic expression of Symbiosis Receptor-like Kinase (SYMRK) in roots of the legume Lotus japonicus resulted in spontaneous activation of nodule organogenesis and mycorrhiza-related gene expression in the absence of microbial symbionts or signalling molecules.
A multi-layered and conserved cell cycle mechanism prevents capsulation, long known as a bacterial virulence determinant, in G1-phase and concurrently licenses bacteriophage-mediated genetic exchange prior to entry into S-phase.
Loss of RUNX1, a key regulator of estrogen receptor-positive luminal breast cells, impairs mammary epithelial differentiation and contributes to luminal breast cancer via genetic interactions with a loss of p53 or RB1.
A previously unrecognized transcriptional coactivator function of the dyskerin ribonucleoprotein complex and its associated small nucleolar RNA has been uncovered and mediates embryonic stem cell-specific transcription.
The formation of mutually exclusive coding and non-coding transcription units contributes to transcriptional interference and insulation at gene clusters and manages state-switching in response to environmental change.
Lrp4 mutant mice display profound deficits in cognitive tasks that assess learning and memory with disruptions in the subcellular organization of synaptic inputs and synaptic plasticity in the hippocampus.
A short treatment of the NOD mouse model of type-1 diabetes with I-BET151, a small molecule bromodomain blocker, provides long-term protection from disease by inducing macrophages to adapt an anti-inflammatory tenor whilst promoting islet β cell regeneration.
The SAGA complex binds non-chromosomal DNA circles and prevents their spreading by attaching them to nuclear pores, thereby leading to the concomitant accumulation of DNA circles and pores in ageing yeast mother cells.
Drep-2 is the first representative of the evolutionary conserved CIDE-N protein family found at synapses and is required for associative learning by functionally intersecting with metabotropic signaling.
The 24 ankyrin repeats of ankyrin proteins form an extended solenoid that provides an extremely conserved groove for binding to numerous targets via combinatorial usage of multiple weak interaction sites.
A novel regulatory step in the endocytic pathway, which occurs post-internalization, takes place at the trans-Golgi network and involves the arrestin-related protein Rod1 and the ubiquitin ligase Rsp5.
Genetic mouse models and human cell lines show that Musashi proteins promote an epithelial/luminal state and inhibit epithelial–mesenchymal transition (EMT), and genome-wide maps of translational regulatory targets connect Musashi proteins to an epithelial alternative splicing program and to the regulation of EMT.
