Functioni

Microtubule plus-end tracking protein that promotes the stabilization of dynamic microtubules. Involved in the nucleation of noncentrosomal microtubules originating from the trans-Golgi network (TGN). Required for the polarization of the cytoplasmic microtubule arrays in migrating cells towards the leading edge of the cell. May act at the cell cortex to enhance the frequency of rescue of depolymerizing microtubules by attaching their plus-ends to cortical platforms composed of ERC1 and PHLDB2. This cortical microtubule stabilizing activity is regulated at least in part by phosphatidylinositol 3-kinase signaling. Also performs a similar stabilizing function at the kinetochore which is essential for the bipolar alignment of chromosomes on the mitotic spindle. Acts as a mediator of ERBB2-dependent stabilization of microtubules at the cell cortex.By similarity1 Publication

Interactioni

Subunit structurei

Interacts with microtubules (PubMed:11290329). Interacts with MAPRE1; probably required for targeting to growing microtubule plus ends. Interacts with ERC1, MAPRE3 and PHLDB2. The interaction with ERC1 may be mediated by PHLDB2. Interacts with GCC2; recruits CLASP2 to Golgi membranes (By similarity). Interacts with CLIP2 and RSN (PubMed:11290329). Interacts with MACF1 (PubMed:18854161).By similarity2 Publications
