CREB3(cAMP responsive element binding protein 3)是一种转录因子,属于CREB/ATF(cAMP response element-binding protein/activating transcription factor)基因家族的一员。这个基因家族的共性在于它们都含有碱性亮氨酸拉链(bZIP)结构域,能够识别并结合特定的DNA序列(如cAMP反应元件CRE),从而调控下游基因的转录。CREB3主要在肝脏、胰腺和脂肪组织中表达,其表达产物在调节内质网应激反应、脂质代谢以及细胞分化等生物学过程中发挥重要作用。CREB3的生物学功能包括参与未折叠蛋白反应(UPR),帮助细胞应对内质网应激,维持蛋白质稳态。此外,它还与葡萄糖代谢和脂肪生成有关,影响机体的能量平衡。CREB3的主要作用位点包括内质网膜,在应激条件下,它会被转运至高尔基体并被蛋白酶切割,释放出具有转录活性的N端片段,进入细胞核调控靶基因的表达。突变对CREB3功能的影响可能导致内质网应激反应失调,进而引发代谢性疾病或神经退行性疾病。例如,CREB3的某些突变与脂肪肝、糖尿病和肥胖等代谢紊乱相关。此外,CREB3在肿瘤发生中也扮演复杂角色,可能通过调控细胞增殖或凋亡相关基因影响癌症进展。如果CREB3过表达,可能增强内质网应激反应,导致细胞凋亡增加,尤其在神经细胞中可能加剧神经退行性病变。过表达还可能干扰脂质代谢,促进脂肪堆积,增加代谢综合征风险。相反,降低CREB3表达可能削弱细胞应对内质网应激的能力,导致错误折叠蛋白积累,影响细胞存活。在肝脏中,CREB3表达不足可能损害脂质代谢,导致脂肪肝或其他代谢异常。CREB3与其他基因的相互作用也值得关注,例如它可能调控SREBP(固醇调节元件结合蛋白)等脂质代谢相关基因的表达,进一步影响机体的代谢平衡。总之,CREB3是一个多功能的转录因子,在细胞应激反应和代谢调控中起关键作用,其表达水平的异常与多种疾病密切相关。

This gene encodes a transcription factor that is a member of the leucine zipper family of DNA binding proteins. This protein binds to the cAMP-response element and regulates cell proliferation. The protein interacts with host cell factor C1, which also associates with the herpes simplex virus (HSV) protein VP16 that induces transcription of HSV immediate-early genes. This protein and VP16 both bind to the same site on host cell factor C1. It is thought that the interaction between this protein and host cell factor C1 plays a role in the establishment of latency during HSV infection. This protein also plays a role in leukocyte migration, tumor suppression, and endoplasmic reticulum stress-associated protein degradation. Additional transcript variants have been identified, but their biological validity has not been determined.[provided by RefSeq, Nov 2009]

这个基因编码的转录因子,它是亮氨酸拉链家族DNA结合蛋白中的一员。这种蛋白质结合营地反应元件,调节细胞增殖。该蛋白质与宿主细胞系数C1,这也与诱导的HSV立即早期基因的转录的单纯疱疹病毒(HSV)蛋白VP16关联相互作用。这种蛋白质与VP16都绑定到宿主细胞因子C1相同的站点。据认为,这种蛋白质和宿主细胞因子C1之间的相互作用发挥HSV感染期间在建立等待时间的作用。这种蛋白质也起着白细胞游走,抑制肿瘤和内质网应激相关蛋白的降解作用。额外转录变异体已经确定,但它们的生物有效性尚未确定。[通过的RefSeq,2009年11月提供]
