The monopolin-like pcs1/mde4 complex is essential for accurate chromosome segregation during mitosis and meiosis II. May clamp together microtubule binding sites on the same kinetochore, preventing merotelic attachment of microtubules. Component of a monopolin-like complex composed of pcs1 and mde4. The complex associates with the kinetochore. Localizes to the central core of the centromere. Transcription is induced by mei4 transcription factor.
