这个基因编码的蛋白质是augmin复合物的一个亚单位。augmin复合物在微管附着于动粒和中心纺锤体形成中起作用。这种蛋白可能通过促进微管依赖的微管扩增而在染色体的有效重组和分离中发挥作用该基因的假基因位于7号和20号染色体上选择性剪接导致编码不同蛋白质亚型的多个转录变体。[由RefSeq提供，2012年8月]
The protein encoded by this gene is a subunit of the augmin complex. The augmin complex plays a role in microtubule attachment to the kinetochore and central spindle formation. This protein may have a role in efficient chromosome congression and segregation by promoting microtubule-dependent microtubule amplification. Pseudogenes of this gene are located on chromosomes 7 and 20. Alternative splicing results in multiple transcript variants that encode different protein isoforms. [provided by RefSeq, Aug 2012]
