Role of Plant Virus Movement Proteins

2008
Plant 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 ...

Motor Proteins and Movement

2007
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 .

Electron Movement Through Proteins and DNA

Free Radical Biology and Medicine, 1997
Nature 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 ‘30K’ superfamily of viral movement proteins

Microbiology, 2000
Relationships among the amino acid sequences of viral movement proteins related to the 30 kDa (‘30K’) movement protein of tobacco mosaic virus – the 30K superfamily – were explored. Sequences were grouped into 18 families. A comparison of secondary structure predictions for each family revealed a common predicted core structure flanked by variable N ...

The movement protein gene is involved in the virus-specific requirement of the coat protein in cell-to-cell movement of bromoviruses

Archives of Virology, 2003
Brome mosaic virus (BMV) requires the coat protein (CP) for cell-to-cell movement whereas Cowpea chlorotic mottle virus (CCMV), from the same genus, does not. Chimeric viruses created by exchanging the movement protein (MP) gene between the viruses can move from cell to cell.

Light‐dependent subcellular movement of photoreceptor proteins

Journal of Neuroscience Research, 1988
AbstractThe 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 ...

Intercellular Protein Movement: Deciphering the Language of Development

Annual Review of Cell and Developmental Biology, 2014
Development in multicellular organisms requires the coordinated production of a large number of specialized cell types through sophisticated signaling mechanisms. Non-cell-autonomous signals are one of the key mechanisms by which organisms coordinate development. In plants, intercellular movement of transcription factors and other mobile signals, such

Transvascular protein movement in the intact ischemic hindlimb

Journal of Surgical Research, 1987
Postischemic limb swelling following reperfusion may be related to microvascular changes associated with ischemia. We used lymph-to-plasma total protein concentration ratios (L/P) and lymph flow (QL) as an index of transvascular exchange in the intact dog hindlimb during steady state (C) (1 hr), ischemia (I) (6 hr), and reperfusion (R) (3 hr).

Leucocytic movement and contractile protein.

Methods and achievements in experimental pathology, 1979
In a study on leucocytic movement, it was found that leucocytes showed periodical dynamic patterns with each motile function, and a possible organization in their motile system. It was also clarified that the motile form and function of leucocytes were co-ordinately controlled by the intracellular level of ATP and that the characteristic contraction ...

Phosphorylation of Movement Proteins by the Plasmodesmal-Associated Protein Kinase

2008
Plant viruses encode movement proteins (MPs) which play important roles in spreading their infectious materials throughout host plants. This infection is facilitated by cell-to-cell trafficking of MPs through specialized channels termed plasmodesmata, which involves specific interactions between MPs and host factors.
