CREBBP(CREB结合蛋白)基因位于人类16号染色体上,属于CBP/p300基因家族。这个家族的特点是编码具有组蛋白乙酰转移酶(HAT)活性的转录共激活因子,能够通过乙酰化组蛋白和其他转录因子来调节基因表达。CREBBP蛋白含有多个功能域,包括与CREB(cAMP反应元件结合蛋白)相互作用的KIX结构域、HAT结构域和溴结构域,这些结构域使其能够参与多种信号通路的调控。CREBBP在细胞分化、增殖、凋亡以及学习和记忆等神经功能中发挥关键作用。它通过与多种转录因子(如p53、NF-κB和STAT)相互作用,调控下游靶基因的表达。CREBBP突变会导致其功能丧失或异常,与多种疾病相关,如Rubinstein-Taybi综合征(RSTS),患者表现为智力障碍、面部特征异常和生长发育迟缓。此外,CREBBP突变也与某些癌症(如急性髓系白血病和淋巴瘤)的发生有关,因为这些突变可能影响其作为肿瘤抑制因子的功能。当CREBBP过表达时,可能增强其转录共激活功能,促进细胞增殖和存活,甚至在某些情况下促进肿瘤发生。相反,降低CREBBP表达可能导致转录调控失衡,影响正常细胞功能,如神经发育和免疫反应。CREBBP与CBP/p300家族的其他成员(如EP300)在功能上有部分冗余,但各自也有独特的调控靶点和生物学作用。该基因家族的共性包括参与表观遗传调控、整合多种信号通路以及广泛影响发育和疾病过程。
This gene is ubiquitously expressed and is involved in the transcriptional coactivation of many different transcription factors. First isolated as a nuclear protein that binds to cAMP-response element binding protein (CREB), this gene is now known to play critical roles in embryonic development, growth control, and homeostasis by coupling chromatin remodeling to transcription factor recognition. The protein encoded by this gene has intrinsic histone acetyltransferase activity and also acts as a scaffold to stabilize additional protein interactions with the transcription complex. This protein acetylates both histone and non-histone proteins. This protein shares regions of very high sequence similarity with protein p300 in its bromodomain, cysteine-histidine-rich regions, and histone acetyltransferase domain. Mutations in this gene cause Rubinstein-Taybi syndrome (RTS). Chromosomal translocations involving this gene have been associated with acute myeloid leukemia. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Feb 2009]
该基因普遍表达,并参与许多不同的转录因子的转录共激活。首先分离出结合于cAMP反应元件结合蛋白(CREB)的核蛋白,该基因是目前已知由染色质重塑耦合到转录因子的识别来在胚胎发育,生长控制和平衡的关键角色。由该基因编码的蛋白质具有固有的组蛋白乙酰转移酶活性和也用作脚手架以稳定与转录复合额外的蛋白质的相互作用。这种蛋白乙酰化既组蛋白和非组蛋白。这种蛋白共享很高的序列相似性的区域,在其布罗莫蛋白P300,富含半胱氨酸 - 组氨酸区域和组蛋白乙酰转移域。突变这个基因导致鲁宾斯坦 - 泰必氏综合症(RTS)。涉及该基因的染色体易位已与急性骨髓性白血病有关。在多个转录剪接变异体导致编码不同亚型。 [由RefSeq的,2009年2月提供]
