Electron Tomography Reveals Novel Microtubule Lattice and Microtubule Organizing Centre Defects in +TIP Mutants

Mal3p and Tip1p are the fission yeast (Schizosaccharomyces pombe) homologues of EB1 and CLIP-170, two conserved microtubule plus end tracking proteins (+TIPs). These proteins are crucial regulators of microtubule dynamics. Using electron tomography, we carried out a high-resolution analysis of the phenotypes caused by mal3 and tip1 deletions. We describe the 3-dimensional microtubule organizati...

The fission yeast gamma-tubulin is essential for mitosis and is localized at microtubule organizing centers.

gamma-Tubulin exists in fission yeast as the product of an essential gene, encoding a 446 amino acid protein that is 77.3% identical to Aspergillus nidulans gamma-tubulin. The gene disruption caused cell lethality, displaying condensed, undivided chromosomes with aberrant spindle structures. Anti-gamma-tubulin staining showed that gamma-tubulin is located, throughout the wild-type cell cycle, a...

Microtubule binding by dynactin is required for microtubule organization but not cargo transport

Dynactin links cytoplasmic dynein and other motors to cargo and is involved in organizing radial microtubule arrays. The largest subunit of dynactin, p150(glued), binds the dynein intermediate chain and has an N-terminal microtubule-binding domain. To examine the role of microtubule binding by p150(glued), we replaced the wild-type p150(glued) in Drosophila melanogaster S2 cells with mutant Del...

Morphological and biochemical characteristics of dreb2a mutant plant grown under normal conditions

DREB transcription factors are one of the largest families of transcription factors in plants that are believed to play important regulatory functions in tolerance to environmental stress, but there is no complete information on their role in controlling the morphological and antioxidant properties of developed plants under normal conditions. In this study, some phenotypic characteristics of th...

QSARS OF ANTI-FUNGAL ACTIVITY OF FURAN CARBOXANILIDE DERIVATIVES AGAINST WILD AND MUTANT STRAINS OF USTILAGO MAYDIS

The structural requirements for the inhibitor activity of various furan carboxanilide derivatives against succinate dehydrogenase complex (SDC) activity in mitochondria of either wild or mutant strains of Ustilago maydis were investigated with the aid of Hansch QSAR analysis. It has been found that the inhibitor activity against both types of enzymes is best related to the ??? or ??M of th...
