GDP-GTP exchange factor for TEM1, a Ras-like protein, component of the mitotic exit network (MEN). Activation of TEM1 by LTE1 in the bud ultimately leads to activation of CDC15 followed by the release of CDC14 from the nucleolus, which then inactivates cyclin-dependent kinases (CDKs) activity by several mechanism. Required for TEM1 localization to the bud cortex during mitotic exit. Fine-tunes the timing of the mitotic exit and couples this event with cytokinesis.
