General annotation (Comments)

Function	Component of the monopolin complex which promotes monoorientation during meiosis I, required for chromosome segregation during meiosis. Plays also a mitotic role in DNA replication. Ref.4 Ref.6 Ref.9 Ref.10 Ref.11
Subunit structure	Component of the monopolin complex composed of at least CSM1, LRS4 and MAM1. The complex associates with the kinetochore. Interacts with CDC46, CDC47, GIC1, GIC2, MCM3 and NUR1. Ref.5 Ref.9 Ref.11
Subcellular location	Nucleus › nucleolus. Chromosome › centromere. Note: Transiently released from the nucleolus and localizes to the centromere regions during late pachytene. Ref.5 Ref.6 Ref.7 Ref.9
Miscellaneous	Present with 1920 molecules/cell in log phase SD medium. Ref.8
