Subcellular location [CC]Nucleus {ECO:0000269|PubMed:24718257}. Chromosome, centromere, kinetochore {ECO:0000269|PubMed:19667759, ECO:0000269|PubMed:21402792, ECO:0000269|PubMed:22110139, ECO:0000269|PubMed:23035123}. Cytoplasm, cytoskeleton, spindle pole {ECO:0000269|PubMed:19667759}. Cytoplasm, cytoskeleton, microtubule organizing center {ECO:0000269|PubMed:29180244}. Note=Colocalizes with microtubules around centrosomes in prophase and with the mitotic spindle at prometaphase and metaphase. From late prometaphase to anaphase, is highly concentrated on kinetochores. Located at the kinetochore-microtubule interface. The astrin (SPAG5)-kinastrin (SKAP) complex localizes to the microtubule plus ends (PubMed:23035123). {ECO:0000269|PubMed:19667759, ECO:0000269|PubMed:21402792, ECO:0000269|PubMed:22110139, ECO:0000269|PubMed:23035123}.
