NCBI Protein Information
microtubule-associated proteins 65-1
NCBI Summary
Binds and bundles microtubules. Plays a role in stabilizing anti-parallel microtubules in the central spindle at anaphase to early cytokinesis but is not essential at the midline of the phragmoplast at later stages. The timing with which the MAP65-1 was targeted to the spindle appears to be regulated by a phosphorylation sensitive switch. Enhances microtubule polymerization, promotes nucleation and stabilizes microtubules against cold treatment and dilution.

UniProt Comments
Microtubule-associated protein that bundle and stabilize adjacent microtubules (MT) of the cell cortex. Enhances MT nucleation. Can also bind to tubulin dimers and promotes their polymerization. Confers MT resistance to the drug propyzamide and cold conditions. Plays a role in the central spindle at anaphase to early cytokinesis but is not essential at the midline of the phragmoplast at later stages. Represses metaphase spindle organization and the transition to anaphase in dephosphorylated active form. Promotes the formation of a planar network of antiparallel microtubules. May be involved in stomatal movement modulation by regulating the dynamic and arrangement of cortical MT.
