Subcellular location [CC]Nucleus {ECO:0000250|UniProtKB:Q920F6}. Chromosome {ECO:0000250|UniProtKB:Q920F6}. Chromosome, centromere {ECO:0000250|UniProtKB:Q920F6}. Note=Associates with chromatin. In prophase I stage of meiosis, localizes along the AE of synaptonemal complexes. In late-pachytene-diplotene, the bulk of protein dissociates from the chromosome arms probably because of phosphorylation by PLK, except at centromeres, where cohesin complexes remain. Remains chromatin associated at the centromeres up to metaphase II. At anaphase II, dissociates from centromeres, allowing chromosomes segregation (By similarity). {ECO:0000250|UniProtKB:Q920F6}.
