这个基因编码的蛋白质是CCR4的一个亚单位，而不是复合物，一个全球转录调节因子编码蛋白与cnot1相互作用，具有e3泛素连接酶活性。已发现该基因的几种编码不同亚型的转录变体。[由RefSeq提供，2010年7月]
The protein encoded by this gene is a subunit of the CCR4-NOT complex, a global transcriptional regulator. The encoded protein interacts with CNOT1 and has E3 ubiquitin ligase activity. Several transcript variants encoding different isoforms have been found for this gene.[provided by RefSeq, Jul 2010]
