Anti-CREB (Ser-271), Phosphospecific Antibody

Name: Anti-CREB (Ser-271), Phosphospecific Antibody
Brand: PhosphoSolutions
SKU: CP4161
Price: 348.0 USD
Availability: InStock

Our CREB (Ser-271) rabbit polyclonal phosphospecific primary antibody from PhosphoSolutions is produced in-house. It detects chicken, human, mouse, and rat CREB (Ser-271) and is antigen affinity purified. It is great for use in WB, ICC.

Western blot analysis of human A431 cells treated with calyculin A (100 nM) for 30 min. (lanes 1, 3, & 5) then blots were treated with lambda phosphatase (lanes 2, 4, & 6). The blots were probed with anti-CREB (N-terminal region) (lanes 1 & 2), anti-CREB (Ser-133) (lanes 3 & 4), and anti-CREB (Ser-271) (lanes 5 & 6).

Immunocytochemical labeling of phosphorylated CREB in control and calyculin A-treated A431 cells. The cells were fixed in paraformaldehyde and permeabilized using NP-40 before labeling with rabbit polyclonal CREB (Ser-271). The antibody was detected using goat anti-rabbit DyLight® 594.

Target

CREB (Ser-271)

Scientific Background

CREB (cyclic AMP response element-binding protein) is a stimulus-induced transcription factor that plays pivotal roles in cell survival and proliferation. CREB is expressed in various tissues, and has important gene-regulating roles in the nervous system. The transactivation function of CREB is primarily regulated through Ser-133 phosphorylation by cAMP-dependent protein kinase A (PKA) and related kinases. CREB is phosphorylated at other sites in response to calcium influx and DNA damage. The DNA-damage responsive nuclear kinase, HIPK2, can phosphorylate Ser-271 but not Ser-133 in CREB, and this phosphorylation activates CREB transactivation function. Mutation of Ser-271 to Glu-271 potentiates the CREB transactivation function. Thus, phosphorylation of Ser-271 may be the mode of activation for CREB-dependent transcription in response to genotoxic stress.

Gene Name

CREB1

Molecular Weight

Immunogen

Phospho-CREB (Ser-271) synthetic peptide (coupled to carrier protein) corresponding to amino acids surrounding Ser-271 in human CREB. This sequence is well conserved in rat, mouse, chicken, and zebrafish CREB. The site has some homology to the conserved site in ATF1 (Ser-198) and CREM (Ser-287).

Specificity

The antibody detects a 43 kDa* protein corresponding to the molecular mass of CREB on SDS-PAGE immunoblots of human A431, Jurkat, and rat PC12 cells treated with Calyculin A, but is not observed after lambda phosphatase treatment.
