Poring over furrows
Cryo-electron microscopy reveals the structure of a chloride channel that is closely related to a protein that transports lipids.
متن کاملPoring over exosome structure.
almost all rNa molecules are pro cessed by rNases to form mature rNas. in addition, many rNas are degraded, either because they are no longer needed or because they are aberrant. all of these functions—rNa processing, normal rNa degradation and rNa quality con trol—are carried out by the eukaryotic rNa exosome complex. in this issue of EMBO reports, the Lorentzen group provide struc tural in...
متن کاملPolarizing for furrows
S plitting mitotic cells in two is not the one-way signaling road it once seemed, based on evidence from Hu et al. The group identifi es a positive feedback loop that creates a furrow at cytokinesis. The fi ndings also throw a wrench in the well-accepted dogma of microtubule dynamic instability. Hu and colleagues devised a monopolar HeLa system to determine how the cytokinetic furrow is created...
متن کاملRappaport Furrows on Our Minds
Cytokinesis presents us with two mysteries: how a cleavage furrow is localized to a single, defined place in the cell; and how an accumulation of proteins can deform a perfectly stable ovoid shape to create two new cells (Fig. 1). Scientists working in varied organisms met recently in Burlington, VT, to address these questions. Each question has a simple answer, although those answers turn out ...
متن کاملSediment Transport in Irrigation Furrows
*Thomas J. Trout, USDA-Agricultural Research Service, Water Management Research Laboratory, 9611 S. Riverbend Ave. Parlier, CA 93658. *Corresponding author: [email protected] ABSTRACT Sediment data were collected in southern Idaho irrigation furrows. Irrigation furrows allow detailed study of sediment transport relationships because of gradually decreasing flow rates in long, uniform, ...
