25 kDa brain-specific protein,brain specific protein p25 alpha,glycogen synthase kinase 3 (GSK3) inhibitor p24,p24,p25,p25alpha,p25-alpha,TPPP/p25,TPPP1,tubulin polymerization-promoting protein.
May play a role in the polymerization of tubulin into microtubules, microtubule bundling and the stabilization of existing microtubules, thus maintaining the integrity of the microtubule network. May play a role in mitotic spindle assembly and nuclear envelope breakdown.
