Smad transcription factors
TLDR
The growing understanding of TGFbeta signaling through the Smad pathway provides general principles for how animal cells translate complex inputs into concrete behavior.Abstract:
Smad transcription factors lie at the core of one of the most versatile cytokine signaling pathways in metazoan biology-the transforming growth factor-beta (TGFbeta) pathway. Recent progress has shed light into the processes of Smad activation and deactivation, nucleocytoplasmic dynamics, and assembly of transcriptional complexes. A rich repertoire of regulatory devices exerts control over each step of the Smad pathway. This knowledge is enabling work on more complex questions about the organization, integration, and modulation of Smad-dependent transcriptional programs. We are beginning to uncover self-enabled gene response cascades, graded Smad response mechanisms, and Smad-dependent synexpression groups. Our growing understanding of TGFbeta signaling through the Smad pathway provides general principles for how animal cells translate complex inputs into concrete behavior.read more

TGF-beta signal transduction.
TL;DR: The transforming growth factor beta (TGF-beta) family of growth factors control the development and homeostasis of most tissues in metazoan organisms and mutations in these pathways are the cause of various forms of human cancer and developmental disorders.

Akt Promotes Cell Survival by Phosphorylating and Inhibiting a Forkhead Transcription Factor

TL;DR: It is demonstrated that Akt also regulates the activity of FKHRL1, a member of the Forkhead family of transcription factors, which triggers apoptosis most likely by inducing the expression of genes that are critical for cell death, such as the Fas ligand gene.

TL;DR: Transforming growth factor-β (TGF-β) proteins regulate cell function, and have key roles in development and carcinogenesis, and combinatorial interactions in the heteromeric receptor and Smad complexes, receptor-interacting and Smadracing proteins, and cooperation with sequence-specific transcription factors allow substantial versatility and diversification of TGF- β family responses.

The Transcriptional Coactivators p300 and CBP Are Histone Acetyltransferases
TL;DR: It is demonstrated that p300/CBP acetylates nucleosomes in concert with PCAF, a novel class of acetyltransferases in that it does not have the conserved motif found among various other acetyl transferases.
