Inhibition of kinesin-driven microtubule motility by monoclonal antibodies to kinesin heavy chains
We have prepared and characterized seven mouse monoclonal antibodies (SUK 1-7) to the 130-kD heavy chain of sea urchin egg kinesin. On immunoblots, SUK 3 and SUK 4 cross-reacted with DrosophilaExpand

Drosophila kinesin: characterization of microtubule motility and ATPase.
Preparations of kinesin, a microtubule-based force-producing protein, have been isolated from Drosophila melanogaster embryos by incubation of microtubules with a nonhydrolyzable ATP analogue and gelExpand

Quantitative analysis of sea urchin egg kinesin-driven microtubule motility.
We have analyzed the effects of various substrates and inhibitors on the rates of microtubule (MT) motility induced by sea urchin egg kinesin using real-time computer analysis and video-enhancedExpand

ENVIRONMENTAL FACTORS INFLUENCING DIATOM CELL MOTILITY 1
This article describes the effect of various environmental conditions on the speed of freshwater diatoms. The diatoms display a wide distribution of cell speeds, from 0 to > 20 μm·s−l, as indicatedExpand

HIGH ENERGY IRRADIATION AT THE LEADING TIP OF MOVING DIATOMS CAUSES A RAPID CHANGE OF CELL DIRECTION
Previous investigations have suggested that the phototactic behaviour of diatoms, as observed by the accumulation of diatoms in low/moderate intensity light spots and avoidance of high intensityExpand

Correlation between the ATPase and microtubule translocating activities of sea urchin egg kinesin
Coupling between ATP hydrolysis and microtubule movement was demonstrated several years ago in flagellar axonemes1,2 and subsequent studies suggest that the relevant microtubule motor, dynein, usesExpand

THE EFFECT OF TEMPERATURE AND MIXED SPECIES COMPOSITION ON DIATOM MOTILITY AND ADHESION
Four species of biraphid pennate diatoms (Craticula cuspidata (Kützing) D.G. Mann, Stauroneis phoenicenteron (Nitzsch) Ehrenberg, Nitzschia linearis (Agardh) W. Smith, and Pinnularia viridisExpand

Chapter 13 Photo-stimulated effects on diatom motility
Abstract Like many unicellular algae, benthic diatoms have active motility to help regulate their access to necessary resources such as light. However, diatom cells are constrained within a hardenedExpand

ECOLOGICAL CONSIDERATIONS OF DIATOM CELL MOTILITY. I. CHARACTERIZATION OF MOTILITY AND ADHESION IN FOUR DIATOM SPECIES 1
To better determine the ecological role of motility in pennate diatoms, we quantitatively characterized several motility and adhesion properties of four species of motile pennate diatoms (CraticulaExpand

USING DIATOM MOTILITY AS AN INDICATOR OF ENVIRONMENTAL STRESS: EFFECTS OF TOXIC SEDIMENT ELUTRIATES
We investigated the possibility of using diatom motility as an indicator for screening potentially toxic sediments. Craticula cuspidata (Kützing) D.G. Mann cells were incubated for up to 4 h inExpand
