Supressor of Ty-16 (SPT16) and structure-specific recognition protein-1 (SSRP1) are subunits of the facilitates chromatin transcription (FACT) complex that is essential for transcription elongation (1,2). FACT facilitates RNA polymerase-dependent transcription of chromatin templates by destabilizing the nucleosomes within the open reading frames of active genes (3-5). FACT destabilizes the nucleosomes, which would otherwise act as barriers to RNA polymerase transcription activity, by disrupting histone-histone and histone-DNA contacts that lead to the eviction of the histone H2A-H2B dimer (2,3,6). FACT may also function as a histone chaperone to reassemble nucleosomes after RNA polymerase passage (7). In addition to transcription, FACT activity has been shown to have a role in DNA replication in yeast and in DNA repair by contributing to the activation of p53 by CK2 and by facilitating histone H2AX-H2B exchange upon DNA damage (8-10).

Supressor of Ty-16 (SPT16)以及structure-specific recognition protein-1 (SSRP1)是转录延伸中至关重要的染色质转录促进复合物的亚单位(1,2)。FACT能够通过对活跃基因开放阅读框内核小体的去稳定作用来促进RNA聚合酶依赖的转录(3-5)。FACT能够破坏导致H2A-H2B二聚体丢失的组蛋白-组蛋白以及组蛋白-DNA的联系,从而使成为RNA聚合酶转录激活障碍的核小体去稳定(2,3,6)。FACT可能还可作为组蛋白伴侣在RNA聚合酶通路之后重新组装核小体(7)。除了转录,FACT还可以通过CK2促进p53活化以及促进DNA损伤的组蛋白H2AX-H2B交换,从而在酵母的DNA复制和DNA修复中发挥作用(8-10)。
