SSRP1(Structure-Specific Recognition Protein 1)是一种重要的基因,编码的蛋白质是FACT复合物(Facilitates Chromatin Transcription)的关键组成部分。FACT复合物由SSRP1和SUPT16H两个亚基组成,主要功能是参与染色质重构(chromatin remodeling),即在DNA复制、修复和转录过程中帮助解开紧密缠绕的染色质结构,使其他蛋白质能够顺利接近DNA。SSRP1通过识别并结合特定的DNA结构(如DNA损伤位点或转录活跃区域)发挥作用,其表达产物具有组蛋白伴侣活性(histone chaperone activity),能暂时移除或替换组蛋白,从而调控基因表达。 SSRP1的突变可能影响其与DNA或组蛋白的相互作用,导致染色质重构异常,进而干扰DNA修复、转录或复制过程。研究表明,SSRP1突变或表达异常与多种癌症(如乳腺癌、结直肠癌)相关,可能通过促进基因组不稳定性或异常细胞增殖来驱动肿瘤发生。此外,SSRP1在胚胎发育中也起关键作用,其缺失可能导致发育缺陷。 当SSRP1过表达时,可能过度激活某些促癌基因的转录,促进肿瘤进展;而降低表达则可能导致DNA修复功能受损,增加细胞对DNA损伤的敏感性,甚至引发细胞凋亡。SSRP1属于FACT基因家族,该家族的共性是通过调控染色质动态变化来影响基因表达、DNA复制和修复。FACT复合物在进化上高度保守,从酵母到人类均存在同源蛋白,表明其在细胞功能中的核心地位。 SSRP1的表达水平还可能影响其他基因的功能,例如与p53(一种抑癌蛋白)的相互作用可能调节细胞周期和凋亡。在癌症治疗中,靶向SSRP1或FACT复合物的策略正在探索中,以期通过干扰肿瘤细胞的染色质稳定性来抑制其生长。

The protein encoded by this gene is a subunit of a heterodimer that, along with SUPT16H, forms chromatin transcriptional elongation factor FACT. FACT interacts specifically with histones H2A/H2B to effect nucleosome disassembly and transcription elongation. FACT and cisplatin-damaged DNA may be crucial to the anticancer mechanism of cisplatin. This encoded protein contains a high mobility group box which most likely constitutes the structure recognition element for cisplatin-modified DNA. This protein also functions as a co-activator of the transcriptional activator p63. An alternatively spliced transcript variant of this gene has been described, but its full-length nature is not known. [provided by RefSeq, Jul 2008]

由该基因编码的蛋白质是,随着SUPT16H一起形成染色质的转??录延伸因子FACT异源二聚体的亚基。事实与组蛋白H2A / H2B专门进行交互,以实现核拆卸和转录延伸。 FACT和顺铂受损的DNA可以是顺铂的抗癌机制是至关重要的。该编码的蛋白含有其中最有可能构成对顺铂修饰的DNA结构的识别元素的高迁移率族。这种蛋白也充当转录激活p63蛋白的共活化剂。这个基因的可变剪接转录物变体进行了说明,但其全长性质是未知的。 [由RefSeq的,2008年7月提供]
