Protein Information (annotations from UniProt)

Database IDHIV0001555
UniProt IDQ8NI77
Primary gene name(s)KIF18A
Synonym gene name(s)unknown
Protein nameKinesin-like protein KIF18A
Protein functionMicrotubule-depolymerizing kinesin which plays a role in chromosome congression by reducing the amplitude of preanaphase oscillations and slowing poleward movement during anaphase, thus suppressing chromosome movements. May stabilize the CENPE-BUB1B complex at the kinetochores during early mitosis and maintains CENPE levels at kinetochores during chromosome congression. {ECO:0000269|PubMed:17346968, ECO:0000269|PubMed:18267093, ECO:0000269|PubMed:18513970, ECO:0000269|PubMed:19625775}.
Subcellular locationCell projection, ruffle. Cytoplasm. Nucleus. Cytoplasm, cytoskeleton, microtubule organizing center, centrosome.
