Centriole structural integrity defects are a crucial feature of hydrolethalus syndrome

Hydrolethalus syndrome (HLS) is a lethal, autosomal recessive ciliopathy caused by the mutation of the conserved centriole protein HYLS1. How HYLS1 controls centriole function is poorly understood. Here, we show that mice harboring the HYLS1 disease mutation die shortly after birth and exhibit developmental defects that recapitulate several manifestations of HLS. These phenotypes arise from […]

RAB-10 cooperates with EHBP-1 to capture vesicular carriers during post-Golgi exocytic trafficking

Post-Golgi exocytic trafficking, fundamental for secretion and cell surface component integration, remains incompletely understood at the molecular level. Here, we investigated this process using Caenorhabditis elegans and mammalian cell models, revealing a novel exocytic carrier capturing mechanism involving the small GTPase RAB-10/Rab10 and its effector EHBP-1/EHBP1. EHBP-1, localized in recycling endosomes, selectively captures RAB-10-positive lipoprotein […]

Prickle2 regulates apical junction remodeling and tissue fluidity during vertebrate neurulation

The process of folding the flat neuroectoderm into an elongated neural tube depends on tissue fluidity, a property that allows epithelial deformation while preserving tissue integrity. Neural tube folding also requires the planar cell polarity (PCP) pathway. Here, we report that Prickle2 (Pk2), a core PCP component, increases tissue fluidity by promoting the remodeling of […]

An S-acylated N-terminus and a conserved loop regulate the activity of the ABHD17 deacylase

The dynamic addition and removal of long-chain fatty acids modulate protein function and localization. The α/β hydrolase domain–containing (ABHD) 17 enzymes remove acyl chains from membrane-localized proteins such as the oncoprotein NRas, but how the ABHD17 proteins are regulated is unknown. Here, we used cell-based studies and molecular dynamics simulations to show that ABHD17 activity […]

Study Reveals Brain Rhythms as Predictors of Seizure Risk in Alzheimer’s

A groundbreaking study by a research team at UCLA Health has revealed critical insights into the connection between brain rhythms and seizure activity in Alzheimer’s disease patients. This research has identified significant changes in brain activity patterns—specifically high-frequency oscillations (HFOs)—which could serve as crucial indicators of epileptic phenomena in individuals grappling with this neurodegenerative illness.

Structure of the F-tractin–F-actin complex

F-tractin is a peptide widely used to visualize the actin cytoskeleton in live eukaryotic cells but has been reported to impair cell migration and induce actin bundling at high expression levels. To elucidate these effects, we determined the cryo-EM structure of the F-tractin–F-actin complex, revealing that F-tractin consists of a flexible N-terminal region and an […]
