The C-terminal region of the micro-tubular organiser protein 1 (mto1) is the binding domain for attachment to Mto2p.The full-length Mto1 protein is required for microtubule nucleation from non-spindle pole body MTOCs in fission yeast [1]. The interaction of Mto2p with this region of Mto1 is critical for anchoring the cytokinetic actin ring to the medial region of the cell and for proper coordination of mitosis with cytokinesis [2].
