Is a fungal transmembrane protein which is part of the component of the spindle pole body (SPB) required for the insertion of the nascent SPB into the nuclear envelope and for the proper execution of spindle pole body (SPB) duplication [1,2,3,4,5,7,8]. It seems that Mps2-Spc24 interaction may contribute to the localisation of Spc24 and other kinetochore components to the inner plaque of the SPB [6].
