這個基因編碼一種對中心體功能重要的蛋白質這種蛋白質對于定位和錨定上皮細胞中的微管負端非常重要。這種蛋白質定位到中心體需要三個亮氨酸拉鏈在中央卷曲線圈域已經報道了編碼不同亞型的多個選擇性剪接轉錄變體[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]
