这个基因编码的蛋白质是丝氨酸/苏氨酸蛋白激酶的polo家族成员，在正常细胞分裂中起作用。该基因在睾丸、脾脏和胎儿组织中表达最为丰富，其表达可由血清诱导，提示该基因在细胞快速分裂过程中也可能发挥重要作用。另外，已经发现该基因编码不同亚型的剪接转录变体。[由RefSeq提供，2011年11月]
The protein encoded by this gene is a member of the polo family of serine/threonine protein kinases that have a role in normal cell division. This gene is most abundantly expressed in testis, spleen and fetal tissues, and its expression is inducible by serum, suggesting that it may also play an important role in cells undergoing rapid cell division. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Nov 2011]
