Protein
65-kDa microtubule-associated protein 3
Organism
Arabidopsis thaliana
Function
Microtubule-associated protein that plays a critical role in organizing the mitotic microtubule array during both early and late mitosis in all plant organs. Essential for the cytokinesis, especially in roots, by maintaining the integrity of the overlapped microtubules in the phragmoplast. Required during root morphogenesis. Needed for giant cell development during root knot nematode infection, where cytokinesis is initiated but not completed.
Similarity
Belongs to the MAP65/ASE1 family.
