Vale Lab /

The Vale Lab at Janelia is studying how molecular motor proteins, kinesin and dynein, transport and govern the intracellular distribution of membranous organelles and how cell signaling impacts these transport processes.

Research Overview

node:body | entity_field

A great deal is known about the atomic structures and biophysical mechanisms of motor proteins. However, much less is known about how motor proteins are regulated by intracellular signals and how such signals impinge upon and coordinately turn on and off kinesin and dynein, two opposite polarity microtubule motor proteins. We are using a synthetic biology approach for tackling these problems by creating artificial cargos that are transported by motor proteins inside of cells and, like natural organelles, are responsive to intracellular signals. Using light microscopy and structural biology approaches, we aim to develop a mechanistic understanding of how motor proteins are regulated.

"Lieutenant," I began eagerly as he was drawing away, "is--?" "My dearest girl, what is the matter?" he asked. It was very quiet and still there when once the gates were closed. Balmayne took one of the lamps from the motor and extinguished the other. In the centre of the place was the well, partially covered over by a flat stone. There was a windlass, but no rope. Balmayne produced one. Very carefully he fitted it to the windlass. His dark eyes gleamed and dilated. A snarling curse came from Balmayne's lips. We now pass to the consideration of Aristotle��s most important achievement��his system of logic. And as, here also, we shall find much to criticise, it is as well to begin by saying that, in our opinion, his contributions to the science are the most valuable ever made, and perhaps have done more to advance it than all other writings on the same subject put together. 93 "Jeff Wilson, the General's Chief Clerk, who belongs to my company," said the Sergeant, "told me yesterday that they wanted another Orderly, and to pick out one for him. I'll send a note for him to detail you right off." There was a rush for another mile or two, when there was a momentary halt to allow a regiment of cavalry to go by at a quick walk. "The hound!" he cried, striking his fists together, "the miserable, cowardy hound!��gone and left me��gone to be a gentleman, the lousy pig. Oh, Lard, I wish as I had him in these hands o' mine!��I'd m?ake a gentleman of him!" "Then, by St. Nicholas! none shall ride here but Richard and myself. Come down, braggart," and he seized the bridle of Newton's horse. HoME ��ѵ�Ի��ŷ��һ��ëƬ��Ƶ ENTER NUMBET 0018zh-hong.com.cn
