CREB5(cAMP responsive element binding protein 5)是一种转录因子,属于CREB/ATF(cAMP response element-binding protein/Activating transcription factor)基因家族。该家族成员通常通过结合DNA上的cAMP反应元件(CRE)来调控基因表达,参与细胞增殖、分化、凋亡以及代谢等过程。CREB5在多种组织中表达,尤其在神经系统、肝脏和免疫系统中发挥重要作用。其表达产物通过与其他蛋白质相互作用,激活或抑制下游靶基因的转录,从而影响细胞的生理功能。CREB5的突变可能导致其功能丧失或异常,进而影响相关信号通路,与多种疾病如癌症、神经退行性疾病和代谢紊乱有关。例如,在某些癌症中,CREB5的异常表达可能促进肿瘤细胞的增殖和侵袭。过表达CREB5可能增强其对下游基因的调控作用,导致细胞生长失控或代谢异常;而降低表达则可能减弱这些调控作用,影响细胞的正常功能。CREB/ATF家族的共性在于它们都含有基本的亮氨酸拉链(bZIP)结构域,能够形成同源或异源二聚体,结合特定的DNA序列来调控基因表达。这一家族成员在应激反应、细胞周期调控和免疫应答等过程中扮演关键角色。CREB5的具体功能仍在研究中,但其在疾病中的作用使其成为潜在的治疗靶点。
The product of this gene belongs to the CRE (cAMP response element)-binding protein family. Members of this family contain zinc-finger and bZIP DNA-binding domains. The encoded protein specifically binds to CRE as a homodimer or a heterodimer with c-Jun or CRE-BP1, and functions as a CRE-dependent trans-activator. Alternatively spliced transcript variants encoding different isoforms have been identified. [provided by RefSeq, Jul 2008]
该基因的产品属结合蛋白家族的CRE(cAMP反应元件)。这个家族的成员含有锌指与DNA的bZIP结合域。所编码的蛋白质特异性结合CRE作为同二聚体或与c-Jun的或CRE-BP1的异二聚体,并且作为CRE依赖性反式激活的功能。编码不同同种型的可变剪接转录物变体也已确定。 [由RefSeq的,2008年7月提供]
