Anti-CREB (Phospho-Ser133) Antibody


Anti-CREB (Phospho-Ser133) Antibody  的详细介绍
Name: Anti-CREB (Phospho-Ser133) Antibody
See all CREB primary antibodies
Description: Rabbit polyclonal antibody to CREB (Phospho-Ser133)
Specificity: The antibody detects endogenous level of CREB only when phosphorylated at serine 133.
Applications: WB, IHC
Dilutions: Western blotting: 1:500~1:1000 Immunohistochemistry: 1:50~1:100
Reactivity: Human, Mouse, Rat
Immunogen: Peptide sequence around phosphorylation site of serine 133 (R-P-S(p)-Y-R) derived from Human CREB.
Host: Rabbit
Clonality: Polyclonal
Conjugate: Unconjugated
Purification: Antibodies were produced by immunizing rabbits with synthetic phosphopeptide and KLH conjugates. Antibodies were purified by affinity-chromatography using epitope-specific phosphopeptide. Non-phospho specific antibodies were removed by chromatogramphy using non-phosphopeptide.
Concentration: 1.0mg / ml
Predicted MW: 43kd
Formulation: Supplied at 1.0mg / mL in phosphate buffered saline (without Mg2+ and Ca2+), pH 7.4, 150mM NaCl, 0.02% sodium azide and 50% glycerol.
Storage: Store at -20°C for long term preservation (recommended). Store at 4°C for short term use.
Function: Phosphorylation-dependent transcription factor that stimulates transcription upon binding to the DNA cAMP response element (CRE), a sequence present in many viral and cellular promoters. Transcription activation is enhanced by the TORC coactivators which act independently of Ser-133 phosphorylation. Involved in different cellular processes including the synchronization of circadian rhythmicity and the differentiation of adipose cells.
Involvement in Disease: Angiomatoid fibrous histiocytoma: A distinct variant of malignant fibrous histiocytoma that typically occurs in children and adolescents and is manifest by nodular subcutaneous growth. Characteristic microscopic features include lobulated sheets of histiocyte-like cells intimately associated with areas of hemorrhage and cystic pseudovascular spaces, as well as a striking cuffing of inflammatory cells, mimicking a lymph node metastasis.
Sequence Similarities: Belongs to the bZIP family.
Post-Translational Modification: Stimulated by phosphorylation. Phosphorylation of both Ser-133 and Ser-142 in the SCN regulates the activity of CREB and participates in circadian rhythm generation. Phosphorylation of Ser-133 allows CREBBP binding. In liver, phosphorylation is induced by fasting or glucagon in a circadian fashion (By similarity). CREBL2 positively regulates phosphorylation at Ser-133 thereby stimulating CREB1 transcriptional activity (By similarity). Phosphorylated upon calcium influx by CaMK4 and CaMK2 on Ser-133. CaMK4 is much more potent than CaMK2 in activating CREB. Phosphorylated by CaMK2 on Ser-142. Phosphorylation of Ser-142 blocks CREB-mediated transcription even when Ser-133 is phosphorylated. Phosphorylated by CaMK1 (By similarity). Phosphorylation of Ser-271 by HIPK2 in response to genotoxic stress promotes CREB1 activity, facilitating the recruitment of the coactivator CBP. Phosphorylated at Ser-133 by RPS6KA3, RPS6KA4 and RPS6KA5 in response to mitogenic or stress stimuli.
Cellular Location: Nucleus.
