Protein
Katanin p60 ATPase-containing subunit A1
Organism
Arabidopsis thaliana
Function
Severs microtubules in vitro in an ATP-dependent manner. This activity may promote rapid reorganization of cellular microtubule arrays. May be required for reorientation of cortical microtubule arrays during cellular elongation. Failure to correctly orient these arrays drastically compromises fiber length, cell wall thickness and mechanical strength. May also be required for the spatial organization of developmental cues within the root.
Similarity
Belongs to the AAA ATPase family. Katanin p60 subunit A1 subfamily.
