NCBI Protein Information
P-loop containing nucleoside triphosphate hydrolases superfamily protein
NCBI Summary
encodes a p60 katanin protein that is expressed throughout the plant. Required for the specification of cell fates from early in development (in the meristem) through differentiation and for normal postmitotic organization of cortical microtubules into transverse arrays in root epidermis cells. Mutants display cytoskeletal defects.

UniProt Comments
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.
