Product details:
Phospho-CREB (S133) and Total CREB ELISA Kit (ab279764) is a very rapid, convenient, and sensitive assay kit that can monitor the activation or function of important biological pathways in human cell lysates. By determining phosphorylated CREB protein in your experimental model system, you can verify pathway activation in your cell lysates. You can simultaneously measure numerous different cell lysates without spending excess time and effort in performing a Western Blotting analysis.
This Sandwich ELISA kit is an
in vitro
enzyme-linked immunosorbent assay for the measurement of Human phospho-CREB and total CREB. An anti-pan CREB antibody has been coated onto a 96-well plate. Samples are pipetted into the wells and CREB present in a sample is bound to the wells by the immobilized antibody and the wells are washed. In select wells, rabbit anti-phospho-CREB (S133) antibody is added to detect phosphorylated CREB. In the remaining wells, mouse anti-pan-CREB antibody is used to detect pan CREB. After washing away unbound antibody, HRP-conjugated anti-rabbit IgG or HRP-conjugated anti-mouse IgG is pipetted into the wells. The wells are again washed, a TMB substrate solution is added to the wells and color develops in proportion to the amount of CREB (S133) or pan CREB bound. The Stop Solution changes the color from blue to yellow, and the intensity of the color is measured at 450 nm.

CAMP response element-binding protein better known as CREB functions as a transcription factor that regulates gene expression. CREB protein operates by binding to specific DNA sequences called cAMP response elements in the promoters of target genes leading to increased or altered transcription. The protein has a molecular weight around 43 kDa. Expressed broadly in many tissues CREB's activity is particularly high in the brain where it plays key roles in neuronal functions. Researchers also refer to phospho-CREB when discussing the activated form of this protein often analyzed through methods like CREB Western blot.
Biological function summary
CREB contributes significantly to cellular processes such as proliferation differentiation and survival through transcriptional regulation. CREB does not function alone; it frequently associates with other proteins forming complexes to exert its regulatory roles. Additionally CREB influences the development of memory and learning in neurons highlighting its extensive involvement in neurophysiological processes.
Pathways
CREB plays a substantial role in the cAMP signaling pathway as well as the mitogen-activated protein kinase (MAPK) pathway. Through its interaction with kinases and other signaling proteins CREB influences numerous downstream targets affecting cellular responses to external stimuli. Notably protein kinase A (PKA) activates CREB by phosphorylation facilitating its role in various signal transduction pathways and linking it to downstream transcriptional events.
Research links CREB to neurological disorders and some forms of cancer. Aberrant CREB activity associates with neurodegenerative diseases like Alzheimer’s where dysregulated gene expression impacts neuronal viability and function. Furthermore in cancer CREB's role in cell proliferation and survival ties it to oncogenes such as BCL2 where abnormal CREB function can promote tumorigenesis. Understanding these connections provides valuable insights for therapeutic strategies against such diseases.
