A tale of two a-tubulin tails
Post-translational modifications of tubulin, such as the removal of the C-terminal tyrosine of a-tubulin, have long been proposed to influence the ability of microtubule motors to walk along the microtubule surface. This hypothesis has now been tested for cytoplasmic dynein-1 (dynein), revealing that active dynein–dynactin– adaptor complexes prefer to start moving on tyrosinated microtubules. T...

‘shield’, considered to be the fish equivalent of the Spemann organizer — and transplanted the cells into host embryos. The result was extra tails, consisting of donoras well as host-derived cells.Agathon et al. also showed that inactivating the Spemann organizer did not interfere with this ‘ectopic’ tail formation, implying that the two organizers are indeed independent. The authors concede, h...
متن کاملTale of tails: parallelism and prehensility.
The occurrence of prehensile tails among only five platyrrhine genera--Cebus, Alouatta, Lagothrix, Ateles, and Brachyteles--might be interpreted as evidence that these are a closely related, possibly monophyletic group. In the absence of behavioral data, it is impossible to test whether all possess equivalent biological roles; such would lend credence to the idea that their tails evolved from a...
متن کاملAn Architectural Tale of the Two Cities
A comparative study of the corresponding styles of Western and Iranian modern architecture has hardly ever been carried out in detail. This paper aims to sketch out an outline for such an investigation and to present a summary of empirical evidence accompanied by field observations to elaborate the ongoing trend of relationship between architectural styles in Iran and that of the West. This is ...
متن کاملAnisotropy for spatial summation of elongated patches of grating: A tale of two tails
Studies of spatial summation often use sinusoidal gratings with blurred edges. When the envelope is elongated (i) along the grating stripes and (ii) at right angles to the grating stripes, we refer to the stimuli as skunk-tails and tiger-tails respectively. Previous work [Polat & Tyler, 1999; Vision Research, 39, 887-895.] has found that sensitivity to skunk-tails is greater than for tiger-tail...
