Here we demonstrate that, unlike phosphorylation, p53 invariably undergoes acetylation in cells ... Full text Link to item Cite

A stimulus-specific role for CREB-binding protein (CBP) in T cell receptor-activated tumor necrosis factor alpha gene expression.

Journal Article Proc Natl Acad Sci U S A · April 11, 2000 The cAMP response element binding protein (CREB)-binding protein (CBP)/p300 family of coactivator proteins regulates gene transcription through the integration of multiple signal transduction pathways. Here, we show that induction of tumor necrosis factor ... Full text Link to item Cite

Gene dose-dependent control of hematopoiesis and hematologic tumor suppression by CBP.

Journal Article Genes Dev · February 1, 2000 Mice with monoallelic inactivation of the CBP gene develop highly penetrant, multilineage defects in hematopoietic differentiation and, with advancing age, an increased incidence of hematologic malignancies. The latter are characterized, at least in some c ... Link to item Cite

SMRTER, a Drosophila nuclear receptor coregulator, reveals that EcR-mediated repression is critical for development.

Journal Article Mol Cell · August 1999 The Drosophila ecdysone receptor (EcR)/ultraspiracle (USP) heterodimer is a key regulator in molting and metamorphoric processes, activating and repressing transcription in a sequence-specific manner. Here, we report the isolation of an EcR-interacting pro ... Full text Link to item Cite

Lineage-specific signaling in melanocytes. C-kit stimulation recruits p300/CBP to microphthalmia.

Journal Article J Biol Chem · July 17, 1998 During melanocyte development, the cytokine Steel factor activates its receptor c-Kit, initiating a signal transduction cascade, which is vital for lineage determination via unknown downstream nuclear targets. c-Kit has recently been found to trigger mitog ...

Distinct roles of the co-activators p300 and CBP in retinoic-acid-induced F9-cell differentiation.

Journal Article Nature · May 21, 1998 The related proteins p300 and CBP (cAMP-response-element-binding protein (CREB)-binding protein)) are transcriptional co-activators that act with other factors to regulate gene expression and play roles in many cell-differentiation and signal transduction ...

Gene dosage-dependent embryonic development and proliferation defects in mice lacking the transcriptional integrator p300.

Journal Article Cell · May 1, 1998 The transcriptional coactivator and integrator p300 and its closely related family member CBP mediate multiple, signal-dependent transcriptional events. We have generated mice lacking a functional p300 gene. Animals nullizygous for p300 died between days 9 ... Full text Link to item Cite

The nuclear hormone receptor coactivator SRC-1 is a specific target of p300.

Journal Article Proc Natl Acad Sci U S A · October 1, 1996 p300 and its family member, CREB-binding protein (CBP), function as key transcriptional coactivators by virtue of their interaction with the activated forms of certain transcription factors. In a search for additional cellular targets of p300/CBP, a protei ... Full text Link to item Cite

Interaction and functional collaboration of p300/CBP and bHLH proteins in muscle and B-cell differentiation.

Journal Article Genes Dev · October 1, 1996 Differentiation of skeletal muscle cells and B lymphocytes is regulated by basic helix-loop-helix (bHLH) proteins. Both differentiation programs are inhibited by the adenovirus E1A oncoprotein. Analysis of E1A mutants has implicated two of its cellular-bin ... Full text Link to item Cite

Ecdysone-inducible gene expression in mammalian cells and transgenic mice.

Journal Article Proc Natl Acad Sci U S A · April 16, 1996 During metamorphosis of Drosophila melanogaster, a cascade of morphological changes is triggered by the steroid hormone 20-OH ecdysone via the ecdysone receptor, a member of the nuclear receptor superfamily. In this report, we have transferred insect hormo ... Full text Link to item Cite

Seven-up inhibits ultraspiracle-based signaling pathways in vitro and in vivo.

Journal Article Mol Cell Biol · December 1995 Seven-up (Svp), the Drosophila homolog of the chicken ovalbumin upstream transcription factor (COUP-TF); Ultraspiracle (Usp), the Drosophila homolog of the retinoid X receptor; and the ecdysone receptor are all members of the nuclear/steroid receptor super ...
