Biology 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 […] Written by Admin February 11, 2025February 11, 2025 Saving Bookmark this article Bookmarked
Biology Mapping Gas Adsorption on Platinum and Gold ‘Crown’ Structures Linked Tokyo Metropolitan University researchers have made significant strides in understanding the behavior of gases interacting with metal cluster-containing crystalline solids. The study focuses on a unique solid compound, [PtAu8(PPh3)8]-H[PMo12O40], identified as PtAu8-PMo12, demonstrating critical insights into how hydrogen and carbon monoxide are absorbed in structures composed of platinum and gold. Using advanced techniques, including quick-scan […] Written by Bioengineer February 9, 2025February 9, 2025 Saving Bookmark this article Bookmarked
Biology VPS41 recruits biosynthetic LAMP-positive vesicles through interaction with Arl8b Vacuolar protein sorting 41 (VPS41), a component of the homotypic fusion and protein sorting (HOPS) complex for lysosomal fusion, is essential for the trafficking of lysosomal membrane proteins via lysosome-associated membrane protein (LAMP) carriers from the trans-Golgi network (TGN) to endo/lysosomes. However, the molecular mechanisms underlying this pathway and VPS41’s role herein remain poorly understood.

Biology Bennu’s Dual-Chirality Amino Acids Spark NASA’s OSIRIS‑REx mission has ushered in a new era in our understanding of prebiotic chemistry and the dynamic nature of small Solar System bodies by returning pristine samples from the near‑Earth asteroid Bennu. In a groundbreaking development that challenges long‑standing assumptions regarding the origins of life on our planet, researchers have discovered that Bennu’s fragments […] Written by Bioengineer February 2, 2025February 2, 2025 Saving Bookmark this article Bookmarked
Biology Sphingolipid metabolism orchestrates establishment of the hair follicle stem cell compartment Sphingolipids serve as building blocks of membranes to ensure subcellular compartmentalization and facilitate intercellular communication. How cell type–specific lipid compositions are achieved and what is their functional significance in tissue morphogenesis and maintenance has remained unclear. Here, we identify a stem cell–specific role for ceramide synthase 4 (CerS4) in orchestrating fate decisions in skin epidermis.

Biology FAM43A coordinates mtDNA replication and mitochondrial biogenesis in response to mtDNA depletion Mitochondrial retrograde signaling (MRS) pathways relay the functional status of mitochondria to elicit homeostatic or adaptive changes in nuclear gene expression. Budding yeast have “intergenomic signaling” pathways that sense the amount of mitochondrial DNA (mtDNA) independently of oxidative phosphorylation (OXPHOS), the primary function of genes encoded by mtDNA. However, MRS pathways that sense the amount […] Written by Admin January 28, 2025January 28, 2025 Saving Bookmark this article Bookmarked
