Electrically mediated protein movement inDrosophila follicles
Roux’s Archives of Developmental Biology, 1988Distribution of rhodamine-conjugated lysozyme injected into the sixteen-cell syncytium comprising the germ-line portion of theDrosophila follicle is shown to be affected by charge. Positive molecules are able to migrate through intercellular bridges from the oocyte to the nurse cells, but are unable to migrate detectably from nurse cells to the oocyte.

Abstract Intracellular movement is an important step for the initial spread of virus in plants during infection. This process requires virus-encoded movement proteins (MPs) and their interaction with host factors. Despite the large number of known host factors involved in the movement of different viruses, little is known about host ...

Role of Plant Virus Movement Proteins
2008Plant viruses spread from the initially infected cells to the rest of the plant in several distinct stages. First, the virus (in the form of virions or nucleic acid protein complexes) moves intracellularly from the sites of replication to plasmodesmata (PD, plant-specific intercellular membranous channels), the virus then transverses the PD to spread ...

Light‐dependent subcellular movement of photoreceptor proteins
Journal of Neuroscience Research, 1988AbstractThe intracellular localization of photoreceptor‐specific proteins 33 kd, beta‐transducin, and 48 kd, as determined by immunocytochemistry, is transient and dependent on the lighting environment to which the retina is exposed. Western analysis of the proteins in isolated rod outer segments from mouse retina demonstrates that beta‐transducin ...

Electron Movement Through Proteins and DNA
Free Radical Biology and Medicine, 1997Nature utilizes the phenomenon of single electron transfer very widely, especially in metallo-proteins. In systems when the metal donor (D) is well separated from the acceptor (A) by polypeptide chains, the transferring electron is presumed to be bonded, in part, by these chains, which may influence the pathway taken.

The cell skeleton forms a scaffold, along which motor proteins can move. These proteins convert the chemical energy of ATP-hydrolysis into mechanical energy. Movement is unidirectional, either from minus to plus or vice versa. The most important systems are microfilament /myosin and microtubule /kinesin and -dynamin .

Structural Mechanisms for Domain Movements in Proteins
Biochemistry, 1994We survey all the known instances of domain movements in proteins for which there is crystallographic evidence for the movement. We explain these domain movements in terms of the repertoire of low-energy conformation changes that are known to occur in proteins.

Epithelial sheet movement: Protein and glycoprotein synthesis
Developmental Biology, 1982Abstract A technique has been developed for organ-culturing rat corneas with a standard epithelial wound and then harvesting epithelium migrating over the wound. Using this technique, we found that corneal epithelium migrating in organ culture incorporates leucine and glucosamine in amounts 45.5 and 11.9 times, respectively, greater than that in ...

Cationic neutrophil proteins increase transendothelial albumin movement
Journal of Applied Physiology, 1987Neutrophils play a role in the development of pulmonary edema in many models of the adult respiratory distress syndrome, but the mechanism of their action is not completely understood. We asked whether two neutrophil secretory products, human neutrophil cationic protein (NCP) and human neutrophil elastase (HNE), would nonenzymatically alter the ...

Movement proteins (MPs) are virally encoded factors that mediate transport of viral nucleic acid between plant cells. Many MPs are able to move between cells themselves. This feature serves as the basis for evaluation of the transport activity of individual MPs.
