Source / Purification

Monoclonal antibody is produced by immunizing animals with a synthetic phosphopeptide corresponding to residues surrounding Ser133 of human CREB.



This Cell Signaling Technology (CST) antibody is conjugated to biotin under optimal conditions. The unconjugated Phospho-CREB (Ser133) (87G3) Rabbit mAb #9198 reacts with human, mouse and rat phospho-CREB (Ser133) protein. CST expects that Phospho-CREB (Ser133) (87G3) Rabbit mAb (Biotinylated) #4095 will also recognize phospho-CREB (Ser133) in these species.

CST公司生产的抗体在最佳条件下与生物素偶联。未偶联的Phospho-CREB (Ser133) (87G3) Rabbit mAb 兔单抗 #9198能与人、小鼠和大鼠的phospho-CREB (Ser133)蛋白反应。CST预计Phospho-CREB (Ser133) (87G3) Rabbit mAb (Biotinylated) #4095也可以识别这些种属的phospho-CREB (Ser133)。

CREB is a bZIP transcription factor that activates target genes through cAMP response elements. CREB is able to mediate signals from numerous physiological stimuli, resulting in regulation of a broad array of cellular responses. While CREB is expressed in numerous tissues, it plays a large regulatory role in the nervous system. CREB is believed to play a key role in promoting neuronal survival, precursor proliferation, neurite outgrowth, and neuronal differentiation in certain neuronal populations (1-3). Additionally, CREB signaling is involved in learning and memory in several organisms (4-6). CREB is able to selectively activate numerous downstream genes through interactions with different dimerization partners. CREB is activated by phosphorylation at Ser133 by various signaling pathways including Erk, Ca2+, and stress signaling. Some of the kinases involved in phosphorylating CREB at Ser133 are p90RSK, MSK, CaMKIV, and MAPKAPK-2 (7-9).

CREB的是一个bZIP转录因子,通过cAMP反应元件激活靶基因。CREB能够介导众多的生理刺激信号,调节很多的细胞反应。CREB的在许多组织中表达,它神经系统起着一个重要的调节作用。CREB被认为在促进特定神经元的存活、增殖、突起生长和神经细胞分化中发挥了关键作用(1-3)。此外,CREB信号在数种生物体中涉及学习和记忆(4-6)。CREB能够通过与不同二聚体相互作用,选择性地激活众多的下游基因。CREB因Ser133的磷酸化而激活,激活可由多种信号通路完成,包括ERK,Ca2+和压力信号。CREB在Ser133的磷酸化所涉及激酶包括p90RSK,MSK,CaMKIV, MAPKAPK-2(7-9)。
