Flow Cytometry
Flow cytometric analysis of SK-N-MC cells using CREB (48H2) Rabbit mAb (blue) compared to a nonspecific negative control antibody (red).
IF-IC
Confocal immunofluorescent analysis of SK-N-MC cells showing nuclear stain with CREB (48H2) Rabbit mAb (A, red) compared to an isotype control (B). Blue pseudocolor =DRAQ5® (fluorescent DNA dye).
IF-F
Confocal immunofluorescent analysis of mouse cerebellum labeled with CREB (48H2) Rabbit mAb (red) and Neurofilament-L (DA2) Mouse mAb #2835 (green). Blue pseudocolor =DRAQ5® #4084 (fluorescent DNA dye).
Chromatin IP
Chromatin immunoprecipitations were performed with cross-linked chromatin from 4 x 106 293 cells, treated with Forskolin #3828 (30 μM) for 1h and either 10 μl of CREB (48H2) 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.
Background
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).
