Enables kinase binding activity. Involved in attachment of mitotic spindle microtubules to kinetochore and mitotic spindle organization. Located in mitotic spindle pole and spindle microtubule. Expressed in germ line. Is an ortholog of human RMDN1 (regulator of microtubule dynamics 1); RMDN2 (regulator of microtubule dynamics 2); and RMDN3 (regulator of microtubule dynamics 3).
Enables transcription coactivator binding activity. Involved in regulation of asymmetric cell division. Located in nucleus. Expressed in several structures, including TL.aa; TL.pa; TR.aa; TR.pa; and hypodermal cell.
