| Short Name | MAP65_Ase1_PRC1 |
| description | This is a family of microtubule associated proteins, including MAP65 (MAP65-1/2/3/4/5/6/7/8/9) from Arabidopsis, Ase1 from yeast, and PRC1 from mammals.Ase1 is required for spindle elongation and stabilisation. It is cell cycle-regulated by anaphase promoting complex []. It is a potential Cdc28p substrate []. MAP65-1 plays a role in stabilising anti-parallel microtubules in the central spindle at anaphase to early cytokinesis. MAP65-1 is cell cycle regulated by phosphorylation [, , , , ].PRC1 is a microtubule binding and bundling protein essential to maintain the mitotic spindle midzone []. It is a key regulator of cytokinesis that cross-links antiparallel microtubules at an average distance of 35 nM [, ]. PRC1 is also required for KIF14 (a kinesin-3 family motor protein) localisation to the central spindle and midbody [, , ]and is required to recruit PLK1 to the spindle. It stimulates PLK1 phosphorylation of RACGAP1/HsCyk-4 to allow recruitment of ECT2 to the central spindle []. |
