EXOSC8（exosome component 8），癌症关联基因，基因ID：11340，这个基因编码一个3'-5'外核糖核酸酶，它与含有富含au元素的mrna特异性相互作用。编码的蛋白质是外显子复合体的一部分，外显子复合体对许多rna物种的降解非常重要。在6号染色体上发现了这个基因的假基因。〔RefSeq，2009〕This gene encodes a 3'-5' exoribonuclease that specifically interacts with mRNAs containing AU-rich elements. The encoded protein is part of the exosome complex that is important for the degradation of numerous RNA species. A pseudogene of this gene is found on chromosome 6. [provided by RefSeq， Mar 2009]。
