CBP and p300 are critical for normal embryonic development
Mouse models CBP and p300 are critical for normal embryonic development, as mice completely lacking either CBP or p300 protein, die at an early embryonic stage. In addition, mice
p300-CBP coactivator family – clinical significance
Mutations in CBP, and to a lesser extent p300, are the cause of Rubinstein-Taybi Syndrome, which is characterized by severe mental retardation. These mutations result in the loss
An example of a process involving p300 and CBP is G protein signaling
Function in G protein signaling Some G proteins stimulate adenylate cyclase that results in elevation of cAMP. cAMP stimulates PKA, which consists of four subunits, two regulat
p300 and CBP are thought to increase gene expression in three ways
Regulation of gene expression p300 and CBP are thought to increase gene expression in three ways: p300 regulates transcription by directly binding to transcription factor
p300-CBP coactivator family
The p300-CBP coactivator family in humans is composed of two closely related transcriptional co-activating proteins (or coactivators): Both p300 and CBP interact wit
Histone acetyltransferase p300
Histone acetyltransferase p300 also known as p300 HAT or E1A-associated protein p300 (where E1A = adenovirus early region 1A) also known as EP300 or p300 is an enzyme t
Rubinstein-Taybi Syndrome (RTS) is a rare genetic disorder that is the result of genetic mutations in either CBP or p300
Rubinstein-Taybi Syndrome (RTS) Type 1, which is caused by CBP mutations, for which over 500 different variations have been documented, accounts for approximately 55% of all cases
CBP has two critical mechanisms by which it is able to regulate gene expression: as an acetyltransferase, and as a protein scaffold
This gene is ubiquitously expressed and is involved in the transcriptional coactivation of many different transcription factors. CBP has two critical mechanisms by which it is a
CBP has been shown to play a role in every stage of tumor development
Due to its critical role in regulation of cell proliferation, growth, migration and apoptosis, it is considered to be an oncogene, or tumor suppressor. Contrarily To date, increa
Proteins shown to interact specifically with CBP (list)
ActrNuclear receptor coactivator ACTR is a novel histone acetyltransferase and forms a multimeric activation complex with P/CAF and CBP/p300.Karamouzis MV, Konstantinopou
CBP has intrinsic acetyltransferase functions
Cyclic adenosine monophosphate Response Element Binding protein Binding Protein (CREB-binding protein), also known as CREBBP or CBP or KAT3A, is a coactivator encoded b
In mouse models of Alzheimer’s Disease, it has been shown that there is a decrease in neuronal histone acetylation, a critical function of CBP
Alzheimer’s Disease (AD) is a progressive neurodegenerative disease whose pathology is diagnosed based on the presence of neuritic amyloid beta (Aβ) plaques and neurofibrill
CREB has been shown to have neuroprotective properties
Because of its association with CBP, understanding the role of CBP in neurological pathways and how aberrations influence disease is becoming of increasing interest. Numerous anima
