Chromatin IP

Chromatin IP

Chromatin immunoprecipitations were performed with cross-linked chromatin from 4 x 106 293 cells treated with Forskolin #3828 (30 µM) and either 10 μl of CREB (D76D11) XP® Rabbit mAb or 2 μl of Normal Rabbit IgG #2729 using SimpleChIP® Enzymatic Chromatin IP Kit (Magnetic Beads) #9003. The enriched DNA was quantified by real-time PCR using human ALS2 exon 1 primers, SimpleChIP® Human Nr4A3 Promoter Primers #4829, and SimpleChIP® Human α Satellite Repeat Primers #4486. The amount of immunoprecipitated DNA in each sample is represented as signal relative to the total amount of input chromatin, which is equivalent to one.

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)。
