該基因編碼的蛋白是一種細胞周期調節激酶，在染色體分離過程中似乎與紡錘體極的微管形成和/或穩定有關。編碼蛋白存在于有絲分裂的間期細胞的中心體和紡錘體兩極。該基因可能在腫瘤的發展和進展中起作用。在1號染色體上發現一個經過加工的假基因，在10號染色體上發現一個未經加工的假基因。已發現該基因的多個編碼相同蛋白質的轉錄變體。
The protein encoded by this gene is a cell cycle-regulated kinase that appears to be involved in microtubule formation and/or stabilization at the spindle pole during chromosome segregation. The encoded protein is found at the centrosome in interphase cells and at the spindle poles in mitosis. This gene may play a role in tumor development and progression. A processed pseudogene of this gene has been found on chromosome 1, and an unprocessed pseudogene has been found on chromosome 10. Multiple transcript variants encoding the same protein have been found for this gene.
