Target Background

Function
AAA1 Antibody functions as an ATP-dependent microtubule severing agent in vitro. It is essential for the oligomerization of functional KTN80-KTN1 complexes, which are responsible for microtubule severing. This activity facilitates rapid reorganization of cellular microtubule arrays. AAA1 Antibody may be crucial for the reorientation of cortical microtubule arrays during cellular elongation. Improper orientation of these arrays significantly compromises fiber length, cell wall thickness, and mechanical strength. Additionally, it may be required for the spatial organization of developmental cues within the root.
Gene References Into Functions
  1. The proteome-wide effects in two KATANIN 1 mutants are reported. PMID: 28706004
  2. Loss of KTN1 prevented random microtubule networks from transitioning into well-ordered arrays. Furthermore, the filamentous actin cap, a characteristic feature of several plant epidermal cell types, including root hairs and leaf trichomes, was absent in the growth apexes of conical cells during cell development. PMID: 28644898
  3. Microtubule severing at cortical microtubule crossover sites was completely abolished in the Arabidopsis katanin mutant. This finding aligns with the observation that GFP-tagged katanin, driven by its native promoter, localizes at sites of CMT crossover prior to severing. PMID: 24206847
  4. A study revealed that microtubule severing by the protein katanin plays a critical and unexpected role in the reorientation of cortical arrays, as triggered by blue light. PMID: 24200811
  5. This study demonstrates that the microtubule-severing protein katanin is essential for coordinating growth between neighboring cells by providing cells with the ability to respond effectively to mechanical stress. PMID: 22500806
  6. The role of katanin, the only known plant microtubule-severing protein, in the organization of cortical microtubules in A. thaliana is reported. PMID: 16805733
