The Handicraft of Cellular Transport Complexes

(PhysOrg.com) -- A protein complex, which is an important link in a cellular transport chain, also initiates the assembly of the next link in the chain. This newly-won insight will now allow a better understanding of a transport ...

New component of a plant steroid-activated pathway discovered

Plant biologists have been working for years to nail down the series of chemical signals that one class of plant hormones, called brassinosteroids, send from a protein on the surface of a plant cell to the cell's nucleus. ...

The long and short of cell signaling

Like a telegraph transmission, the significance of a cellular signal can change greatly depending on whether it arrives as a brief 'dot' or a sustained 'dash'. For example, transient activation of extracellular receptor kinase ...

Researchers find cells move in mysterious ways (w/ Video)

Our cells are more like us than we may think. They're sensitive to their environment, poking and prodding deliberately at their surroundings with hand-like feelers and chemical signals as they decide whether and where to ...

Blowfly protein key to terror poison antidote

A protein that costs the Australian sheep industry hundreds of millions of dollars each year may also pave the way to an antidote for chemical warfare agents.

Protein structure reveals how cells regulate their skeletons

Insight into the regulation of cell skeleton structure has come from a study conducted by A*STAR researchers. The work, which solved a protein structure that has eluded scientists for 20 years, should lead to further insights ...

New procedure allows long-term culturing of adult stem cells

A new procedure developed at Massachusetts General Hospital (MGH) may revolutionize the culturing of adult stem cells. In their report that has been published online prior to its appearance in the August 6 issue of Cell Stem ...
