Katanin function
Webb Katanin function during corticogenesis and in neural morphology. (A) During mouse corticogenesis, the katanins regulate asymmetrical proliferation, cellular migration, and neuron development. Webb19 apr. 1999 · These results indicate that microtubule-severing by katanin is essential for releasing microtubules from the neuronal centrosome, and also for regulating the length of the microtubules after their release. A xons and dendrites contain dense arrays of highly organized microtubules.

WebbFunction Catalytic subunit of a complex which severs microtubules in an ATP-dependent manner. Microtubule severing may promote rapid reorganization of cellular microtubule arrays and the release of microtubules from the centrosome following nucleation. Katanin-mediated microtubule severing is an important step in mitosis and meiosis. It has been shown that katanin is responsible for severing microtubules during M-phase in Xenopus laevis. The disassembly of microtubules from their interphase structures is necessary to prepare the cell and the mitotic spindle … Visa mer Katanin is a microtubule-severing AAA protein. It is named after the Japanese sword called a katana. Katanin is a heterodimeric protein first discovered in sea urchins. It contains a 60 kDa ATPase subunit, … Visa mer Katanin is important in the development of many organisms. Both elimination and overexpression of katanin is deleterious to axonal growth, … Visa mer • Microtubule-severing ATPase Visa mer • Hartman, Jim. "Katanin, an AAA ATPase that Takes Apart Stable Microtubules." 2004. • McNally Lab research. "katanin" 2006 Visa mer Structural analysis using electron microscopy has revealed that microtubule protofilaments change from a straight to a curved conformation upon GTP hydrolysis of β-tubulin. However, when these protofilaments are part of a polymerized microtubule, the … Visa mer Katanin is known to be abundant in the nervous system and even modest levels of it can cause significant microtubule depletion. But … Visa mer Katanin is also found to have similar functions in higher plants. The form and structure of a plant cell is determined by the rigid cell wall, which contains highly organized cellulose, the orientation of which is affected by microtubules that serve to guide the … Visa mer
Webb21 nov. 2024 · KATANIN is a well-studied microtubule severing protein affecting microtubule organization and dynamic properties in higher plants. By regulating mitotic and cytokinetic and cortical microtubule arrays it is involved in the progression of cell division and cell division plane orientation.
