The PAF (RNA polymerase II (RNAPII) associated factor) complex was initially identified in yeast and is comprised of subunits PAF1, Leo1, Ctr9, Cdc73, RTF1 and Ski8 (1,2). The PAF complex plays an important role in transcription initiation and elongation by RNAPII by regulating the establishment of proper histone modifications such as histone H2B ubiquitination and the recruitment of the histone chaperone FACT (facilitates chromatin transcription) (3-5). The PAF complex also plays a role in mRNA processing and maturation by interacting with, and recruiting, the cleavage and polyadenylation specificity factor and cleavage stimulation factor complexes via the Cdc73 subunit. (6,7). In addition, the Ski8 subunit of the PAF complex is part of the hSKi complex, which regulates RNA surveillance, suggesting an important function of the complex in coordinating events associated with proper RNA maturation during transcription (1,8).

PAF(RNA polymerase II (RNAPII) associated factor)复合物最初是在酵母中被鉴定出来的,由PAF1, Leo1, Ctr9, Cdc73, RTF1 和Ski8 (1,2)组成(1,2)。PAF复合物是RNAPII街道的转录起始和延伸过程中一个非常重要的角色,RNAPII可调控如组蛋白H2B泛素化等正确的组蛋白修饰的确立,还可以调控组蛋白伴侣FACT( facilitates chromatin transcription)的募集(3-5)。同时,PAF复合物还在mRNA加工和成熟过程中扮演重要的角色,因为它可以通过Cdc73亚基与剪切和多聚腺苷酸化特异性因子以及剪切刺激因子复合物相互作用,并募集他们(6,7)。另外PAF复合物的Ski8亚基还是hSKi复合物的一部分,而hSKi复合物能够调控RNA监控,这意味着PAF复合物在转录期间与与正确的RNA成熟有关的协调事件中发挥重要功能(1,8)。
