 | New findings from researchers at Harvard Medical School in Boston and the Hospital for Sick Children in Toronto may shed light on the mechanisms that regulate the organization of receptors on the cell surface, a critical aspect of cell signaling not well understood at this time. ...> Full Article |
New research sheds light on the interaction between the semi-flexible protein tropomyosin and actin thin filaments. The study, published by Cell Press on Feb. 15 in the Biophysical Journal, provides the first detailed atomic model of tropomyosin bound to actin and significantly advances the understanding of the dynamic relationship between these key cellular proteins.

A new study reveals that muscle cells fuse together during development by poking "fingers" into each other to help break down the membranes separating them. The study appears online on Nov. 22, 2010 in the Journal of Cell Biology.

Researchers at Huntsman Cancer Institute at the University of Utah have discovered that a protein, zyxin, is necessary for the maintenance and repair of the cell's cytoskeleton, or internal framework, which serves as the muscle and bone of the cell.

 | University of Illinois researchers have demonstrated a new model for the motion of actin filaments, the molecules that give a cell its structure. Researchers have long assumed that actin filaments could move anywhere within a confined cylinder of space, like a snake slithering through a pipe. However, this study shows that a filament moves more like a conga line on a crowded dance floor: sometimes it's a tight squeeze. ...> Full Article |
