A budding role for a cellular dynamo
Date:2/18/2009

The researchers discovered that a protein called Bud14 is a potent inhibitor, directly binding to the formin and displacing it, thereby producing actin filaments of normal length, a prerequisite for proper actin cable architecture and cargo transport.

"In all animal, plant, and human cells, life depends on rapidly producing actin filaments of defined lengths, and we now have an important clue as to how this is regulated," said Goode. "We're now homing in on the precise mechanism by which Bud14 works and extending this analysis to mammalian cells. Once again, yeast has provided the ideal system in which to pioneer a basic problem that applies to most other species."
