Under normoxic conditions, the SUMOylated fraction of TFAP2A cannot interact with the Ku70/Ku80 complex, nor it can bind to chromatin. The unSUMOylated fraction pre‐occupies the chromatin of a subset of hypoxia‐induced genes together with the Ku70/Ku80 complex for basal euchromatin formation. Under hypoxic conditions, the SUMOylation equilibrium shifts

Rabbit reticulocyte eukaryotic initiation factor 2 was phosphorylated with the heme-regulated alpha subunit of eukaryotic initiation factor 2 kinase, and then the individual subunits were resolved by reversed-phase high performance liquid chromatography. Phosphorylated and unphosphorylated forms of the alpha subunit also were well resolved.

Phase Separation: A New Dimension to Understanding Tumor Biology and Therapy
Liquid–liquid phase separation (LLPS) facilitates the assembly of biomolecular condensates by leveraging weak multivalent interactions. The low‐complexity domains, foldable domains of proteins, and nucleic acids provide multivalent interaction sites among different molecules and contribute to the formation of condensates.

Regulation of the mTOR Complex 1 Pathway by Nutrients, Growth Factors, and Stress [PDF]
The large serine/threonine protein kinase mTOR regulates cellular and organismal homeostasis by coordinating anabolic and catabolic processes with nutrient, energy, and oxygen availability and growth factor signaling.

ER stress in antigen‐presenting cells promotes NKT cell activation through endogenous neutral lipids [PDF]
CD1d-restricted invariant natural killer T (iNKT) cells constitute a common glycolipid-reactive innate-like T-cell subset with a broad impact on innate and adaptive immunity.

Orchestrating Neural Development Through mRNA Translation Regulation
This review provides an overview of mRNA translation mechanisms that control prenatal brain development, including cortical lamination, progenitor differentiation, and axon guidance, and identifies significant knowledge gaps. Specifically, we focus on mRNA translation regulation through signaling cascades such as the mammalian/mechanistic target of ...

Nutrient availability is a key determinant of tumor cell behavior. While nutrient‐rich conditions favor proliferation and tumor growth, scarcity, and particularly glutamine starvation, promotes cell dedifferentiation and chemoresistance.

Uncharged tRNA Activates GCN2 by Displacing the Protein Kinase Moiety from a Bipartite tRNA-Binding Domain [PDF]
Protein kinase GCN2 regulates translation in amino acid–starved cells by phosphorylating eIF2. GCN2 contains a regulatory domain related to histidyl-tRNA synthetase (HisRS) postulated to bind multiple deacylated tRNAs as a general sensor of starvation ...
