Component of the CENPA-CAD (nucleosome distal) complex; a complex recruited to centromeres which is involved in assembly of kinetochore proteins; mitotic progression and chromosome segregation. May be involved in incorporation of newly synthesized CENPA into centromeres via its interaction with the CENPA-NAC complex. Required for the localization of CENPF; MAD1L1 and MAD2 (MAD2L1 or MAD2L2) to kinetochores. Involved in the response of gonadal tissues to follicle-stimulating hormone (By similarity). {ECO:0000250}.
