Scientific Background: AurC (AurKC) is a protein-serine/threonine kinase of the Other group and AUR family. It serves an essential component of the chromosomal passenger complex (CPC), which functions to ensure correct chromosomal alignment and segregation during mitosis. In addition, this protein complex is necessary for chromatin-induced microtubule stabilization and formation of the spindle apparatus. AurC has also been shown to play a key role in meiosis, specifically during spermatogenesis (production of sperm). Several mutations in the AurC gene have been observed in male patients with spermatogenic failure 5, including a 1-bp deletion (144delC) leading to premature translation termination at position 71 and a truncated protein without a catalytic domain, a C229Y substitution mutation in the kinase catalytic domain of the protein, and a 2A-to-G transition mutation at the splice site of intron 4 (436-2A-G) leading to the omission of exon 5 from the protein. These mutations result in a loss-of-function for the protein catalytic activity, therefore defects in AurC activity are thought to be the primary contributing factor to the development of spermatogenic failure 5.
