MAPRE3 (Q9UPY8) - Overview - Molecular Target Synopsis


MAPRE3, Microtubule-associated protein RP/EB family member 3
UniProt Q9UPY8

Also Known as MARE3_HUMAN, MAPRE3

Plus-end tracking protein (+TIP) that binds to the plus-end of microtubules and regulates the dynamics of the microtubule cytoskeleton. Promotes microtubule growth. May be involved in spindle function by stabilizing microtubules and anchoring them at centrosomes. Also acts as a regulator of minus-end microtubule organization: interacts with the complex formed by AKAP9 and PDE4DIP, leading to recruit CAMSAP2 to the Golgi apparatus, thereby tethering non-centrosomal minus-end microtubules to the Golgi, an important step for polarized cell movement (PubMed:28814570). Promotes elongation of CAMSAP2-decorated microtubule stretches on the minus-end of microtubules (PubMed:28814570). May play a role in cell migration. Interacts with APC2 (PubMed:10644998). Homodimer (PubMed:19255245). Heterodimer with MAPRE1 (PubMed:19255245). Interacts with DCTN1 and SRCIN1 (PubMed:14514668, PubMed:19146815). Binds to the C-terminal domain of APC (PubMed:14514668). Binds monomeric and polymerized tubulin (PubMed:10188731). Interacts (via C-terminus) with CLIP1 (PubMed:17563362). Interacts with SLAIN2 and SLAIN1 (PubMed:21646404). Interacts with AKAP9 (PubMed:28814570). Interacts with PDE4DIP (PubMed:28814570). Interacts with PDE4DIP isoform 13/MMG8/SMYLE; this interaction is required for its recruitment to the Golgi apparatus (PubMed:25217626).
