Involved in chromosome segregation. Facilitates nuclear oscillation during meiotic prophase I, the 'horsetail' phase, by acting as a dynein anchor. Essential for anchoring dhc1 to the cortex. Required for proper sliding of the microtubules along the cell cortex, which leads to the proper U-turn movement of the nucleus. Localizes to the cell cortex during the 'horsetail' phase of mitosis.
