这个基因编码一种对中心体功能重要的蛋白质这种蛋白质对于定位和锚定上皮细胞中的微管负端非常重要。这种蛋白质定位到中心体需要三个亮氨酸拉链在中央卷曲线圈域已经报道了编码不同亚型的多个选择性剪接转录变体[由RefSeq提供，2008年7月]
This gene encodes one of the proteins important for centrosomal function. This protein is important for positioning and anchoring the microtubules minus-ends in epithelial cells. Localization of this protein to the centrosome requires three leucine zippers in the central coiled-coil domain. Multiple alternatively spliced transcript variants that encode different isoforms have been reported. [provided by RefSeq, Jul 2008]
