Summary: Endocytosis of many cell surface proteins is triggered following glucose starvation, with recovery from starvation mediated by a small fraction of nutrient transporters preserved at the surface in eisosomes.

Errors in mitotic chromosome segregation can lead to DNA damage and aneuploidy, both hallmarks of cancer. To achieve synchronous error-free segregation, mitotic chromosomes must align at the metaphase plate with stable amphitelic attachments to microtubules emanating from opposing spindle poles. The Astrin-Kinastrin/SKAP complex, also containing DY...

Approximately 15% of autosomal dominant polycystic kidney disease (ADPKD) is caused by variants in PKD2 PKD2 encodes polycystin-2, which forms an ion channel in primary cilia and endoplasmic reticulum (ER) membranes of renal collecting duct cells. Elevated internal Ca2+ modulates polycystin-2 voltage dependent gating and subsequent desensitization-...

Eukaryotic cells have evolved organelles that allow the compartmentalization and regulation of metabolic processes. Knowledge of molecular mechanisms that allow temporal and spatial organization of enzymes within organelles is therefore crucial for understanding eukaryotic metabolism. Here, we show that the yeast malate dehydrogenase 2 (Mdh2) is du...

Both functional and dysfunctional mitochondria are known to underlie tumor progression. Here, we establish use of the proto-oncogene Drosophila Homeodomain-interacting protein kinase (Hipk) as a new tool to address this paradox. We find that, in Hipk-overexpressing tumor-like cells, mitochondria accumulate and switch from fragmented to highly fused...

Summary: Crosstalk between endophilin-A2 and caveolin-1, proteins implicated in clathrin-independent endocytosis, regulates a tubular endocytic pathway important for plasma membrane repair and trypanosome invasion.
