The WT1–BASP1 complex is required to maintain the differentiated state of taste receptor cellsThe WT1/BASP1 complex is important to maintain taste receptor cells in their terminally differentiated state.
Opposing functions of F-BAR proteins in neuronal membrane protrusion, tubule formation, and neurite outgrowthNeurite formation is a fundamental antecedent to axon and dendrite formation, but the mechanisms that underlie this important process are poorly characterized. Here, we demonstrate that two F-BAR proteins, CIP4 and FBP17, have opposing functions in early cortical neuron development.
PKAc is not required for the preerythrocytic stages of Plasmodium bergheiThe mutant salivary gland sporozoites lacking PKAc are able to glide, invade hepatocytes, and mature into hepatic merozoites, which release successfully from the merosome, however, fail to initiate blood stage infection when inoculated into mice.
Molecular characterization of CHAD domains as inorganic polyphosphate-binding modulesA domain of unknown function termed CHAD, present in all kingdoms of life, is characterized as a specific inorganic polyphosphate-binding domain.
Loss of PGC-1α in RPE induces mesenchymal transition and promotes retinal degenerationSustained loss of PGC-1α in RPE cells triggers mitochondrial/autophagic dysfunction and oxidative damage resulting in epithelial dedifferentiation and mesenchymal transition. RPE dysfunction caused by deletion of the PGC-1 coactivators in vivo causes retinal degeneration.
An N-terminal–truncated isoform of FAM134B (FAM134B-2) regulates starvation-induced hepatic selective ER-phagyThis study has identified a novel truncated isoform of FAM134B (FAM134B-2) that regulates starvation-induced selective ER-phagy of secretory proteins such as ApoCIII through the activation of C/EBPβ.
Cellular response upon proliferation in the presence of an active mitotic checkpointCells that replicate with an active mitotic checkpoint remain capable to mount multiple times an efficient arrest, are bigger than unperturbed cells, rely more heavily on Cdh1, and have an altered protein expression profile.
Competition in the chaperone-client network subordinates cell-cycle entry to growth and stressGrowth and cell-cycle entry compete for multifunctional chaperones subjugating the critical size and proliferation to the growth potential of the cell.
Inhibition of the deubiquitinase USP8 corrects a Drosophila PINK1 model of mitochondria dysfunctionAberrant mitochondrial dynamics contribute to disease conditions. Genetic and pharmacological inhibition of USP8 ameliorates mitochondrial phenotypes deriving from loss of function of Drosophila PINK1 and Parkin.
An extracellular matrix protein promotes anillin-dependent processes in the Caenorhabditis elegans germlineThe extracellular matrix protein Hemicentin (HIM-4) is an extracellular factor that regulates anillin (ANI-1) for germ cell membrane stabilization and contractile ring formation in C. elegans germline cells.
