- | '''Stathmin-4''' (STM-4) regulates microtubules dynamics. Microtubules undergo continuous assembly and disassembly in the cell’s cytoskeleton. STM-4 binds to tubulin and prevents the latter from polymerization thus preventing microtubule assembly. Phosphorylation of STM-4 weakens the binding of STM-4 to tubulin enabling the microtubule assembly needed for the formation of mitotic spindle. Thus, STM-4 is an oncoprotein. STM-4 contains an SLD (Stathmin-Like Domain) domain of 149 residues which binds the tubulin dimer<ref>PMID:15216892</ref>. | + | '''Stathmin-4''' (STM-4) or '''stathmin-like protein B3''' regulates microtubules dynamics.
