果蝇曲颈基因（crn）是胚胎发生的关键基因，被认为参与细胞周期的进程和mrna前剪接。由这个人类基因座编码的蛋白质被发现定位于细胞核中的前mrna剪接复合物，是前mrna剪接所必需的。另外，已经描述了剪接转录变体。[由RefSeq提供，2013年7月]
The crooked neck (crn) gene of Drosophila is essential for embryogenesis and is thought to be involved in cell cycle progression and pre-mRNA splicing. A protein encoded by this human locus has been found to localize to pre-mRNA splicing complexes in the nucleus and is necessary for pre-mRNA splicing. Alternatively spliced transcript variants have been described. [provided by RefSeq, Jul 2013]
