Latest Microfilament Stories
In this study, Shuichi Takeda at Nagoya University and colleagues present the X-ray crystal structures of the actin capping protein (CP) complexed with its inhibitors, V-1 and CARMIL, and demonstrate that the two regulators modulate the filament capping activity in very different manners.
The APC protein serves as the colon's guardian, keeping tumors at bay.
Understanding the steps to the intricate dance inside a cell is essential to one day choreographing the show.
Novel method distinguishes between structurally similar folding forms
A group of Marshall University researchers and their colleagues in Japan are conducting research that may lead to new ways to move or position single moleculesâ€”a necessary step if man someday hopes to build molecular machines or other devices capable of working at very small scales.
A network of proteins underlying the plasma membrane keeps epithelial cells in shape and maintains their orderly hexagonal packing in the mouse lens, say Nowak et al. The study will appear in the September 21, 2009 issue of the Journal of Cell Biology (online September 14).
Memories aren't made of actin filaments. But their assembly is crucial for long-term potentiation (LTP), an increase in synapse sensitivity that researchers think helps to lay down memories.
Researchers from the Ludwig Institute for Cancer Research at the University of California, San Diego School of Medicine have identified a key step required for cell division in a study that could help improve therapies to treat cancer.
Flip open any biology textbook and you're bound to see a complicated diagram of the inner workings of a cell, with its internal scaffolding, the cytoskeleton, and how it maintains a cellâ€™s shape.
Researchers at the University of Pennsylvania School of Medicine have discovered that a protein called leiomodin (Lmod) promotes the assembly of an important heart muscle protein called actin. Whatâ€™s more, Lmod directs the assembly of actin to form the pumping unit of the heart. The findings appear in this weekâ€™s issue of Science.
- One who brings meat to the table; hence, in some countries, the official title of the grand master or steward of the king's or a nobleman's household.
