Cell News—Cells store extra membrane to keep up with supply and demand

Cells store extra membrane along pits and protrusions in the cell surface. But how cells regulate those membrane stores is not well understood. ASCB members Lauren Figard, Anna Marie Sokac, and colleagues at the Baylor College of Medicine monitored membrane supply and demand in Drosophila  … Read more

Cell News—Endoplasmic reticulum protein involved in plasma membrane lipid regulation

Organelles once thought to be independent are coming to light as allies. Research in the last few years has built evidence that interactions between the endoplasmic reticulum and the plasma membrane play a role in lipid synthesis. However, the molecular mechanisms are still being investigated.  … Read more

Cell News—Signaling OK to exit mitosis when spindle is aligned

In budding yeast if the mitotic spindle isn’t properly aligned, the cells won’t divide. But whether the cell signaling causes a halt in mitosis when the spindle is misoriented, or whether a properly oriented spindle causes mitosis to proceed was not known. Now Jill Falk  … Read more

Cell News—Yeast lifestyles affect responses to stress

Even yeast get stressed. The environmental stress response of Saccharomyces cerevisiae, the yeast used for wine-, beer-, and bread-making and model organisms in the lab, has been well studied. But whether its stress responses are unique to this species of yeast, or common in all  … Read more

Cell News—Tango lessons for big guys from Barcelona

There has been a rather large hole in our understanding of how the endoplasmic reticulum (ER), the cell’s protein and lipid assembly plant, manages to export very large molecules. A whole array of important but bulky proteins are simply too big to be exported inside  … Read more

Cell News—Mapping translation in live cells

Messenger RNAs (mRNAs) code gene protein products and are highly mobile within the cell.   While researchers have been able to track mRNA movement, it wasn’t possible to see which of these mRNAs were actively translating to proteins. Now Zachary Katz and colleagues in ASCB member  … Read more

Cell News—Septins can spot the big stuff in cell shape

Cells are shape shifters, rearranging themselves for diverse functions from cell division to sprouting a flagellum. But how does a cell know what shape it’s in? We’ve known that proteins can sense cellular contours on the nano scale, that is, 1 x 10-9 m, but  … Read more

Cell News—How a rare class of antibodies neutralizes the HIV-1 virus

The Holy Grail in the search for an HIV-1 vaccine is the “broadly neutralizing antibody” or bNAb. The target for all immune antibodies attacking HIV-1 is the virus’s glycoprotein envelope (Env), which is a complicated twist of two proteins, gp120 and gp41. The resulting Env  … Read more

Cell News—Seeing the leaves for the forest

Did you have a high school biology teacher who was keen on taxonomy and keying out tree species? If you discovered that the real forest and the keyed forest in your handbook didn’t always match, you might enjoy an ingenious new paper in PNAS from  … Read more
