The protein EP300 and its paralog CREBBP (CREB-binding protein) are ubiquitously expressed transcriptional co-activators and histone acetyl transferases. The gene EP300 is essential for normal cardiac and neural development, whereas CREBBP is essential for neurulation, hematopoietic differentiation, angiogenesis and skeletal and cardiac development.(More)
The CITED family proteins bind to CBP/p300 transcriptional integrators through their conserved C-terminal acidic domain and function as coactivators. The 21-kDa mouse Cited4 protein, a novel member of the CITED family, interacted with CBP/p300 as well as isoforms of the TFAP2 transcription factor, coactivating TFAP2-dependent transcription. The cited4 gene(More)
Many aspects of physiology and behavior follow a circadian rhythm. Brain and muscle Arnt-like protein-1 (BMAL1) is a key component of the mammalian molecular clock, which controls circadian oscillations. In the rat, the gene encoding Bmal1 is located within hypertension susceptibility loci. We analyzed the SNP distribution pattern in a congenic interval(More)
The interaction of hypoxia-inducible factor 1alpha and the CH1 domain of the transcriptional coactivator p300/CBP is necessary for the expression of hypoxia responsive genes and tumor angiogenesis. The transcription factor CITED2 binds p300/CBP at the CH1 domain and functions as a negative regulator of hypoxia signaling by competing with hypoxia-inducible(More)
CITED2 is a transcriptional co-activator with 3 conserved domains shared with other CITED family members and a unique Serine-Glycine Rich Junction (SRJ) that is highly conserved in placental mammals. Loss of Cited2 in mice results in cardiac and aortic arch malformations, adrenal agenesis, neural tube and placental defects, and partially penetrant defects(More)
The objective was to develop a program for inducing estrus (followed by insemination) of suckled beef cows under nutritional stress (poor body condition). A total of 123 cows, from 60 to 75 days postpartum, were classified according to their body condition score (BCS; range from 1 to 5, in increments of 0.5) and allocated into two groups. On Day 0 (without(More)
Malformations of the septum, outflow tract and aortic arch are the most common congenital cardiovascular defects and occur in mice lacking Cited2, a transcriptional coactivator of TFAP2. Here we show that Cited2(-/-) mice also develop laterality defects, including right isomerism, abnormal cardiac looping and hyposplenia, which are suppressed on a mixed(More)
The transcriptional co-activators and histone acetyltransferases p300/CREB-binding protein (CBP) interact with CITED2, a transcription factor AP-2 (TFAP2) co-activator. p300/CBP, CITED2, and TFAP2A are essential for normal neural tube and cardiac development. Here we show that p300 and CBP co-activate TFAP2A in the presence of CITED2. TFAP2A transcriptional(More)
Transcription of the murine interferon-A4 (IFN-A4) gene is mediated by a virus responsive element (VRE-A4) located in the promoter proximal [-120 to -43] region. VRE-A4 contains four DNA modules (A to D) which cooperate for maximal IFN-A4 activation following virus infection. The differential expression between the highly expressed IFN-A4 and the weakly(More)
Members of the CREB-binding protein/p300-interacting transactivator with ED-rich tail (CITED) family bind CREB-binding protein and p300 with high affinity and regulate gene transcription. Gene knockout studies indicate that CITED2 is required for neural crest and neural tube development and that it functions as a co-activator for transcription factor AP-2(More)
