Ubiquitin News and Research

RSS

Ubiquitin is a small regulatory protein that has been found in almost all cells (''ubiquitously'') with nuclei (eukaryotes). It directs proteins to recycling and other functions.

SonoPIN technology boosts intracellular delivery of large cancer drugs

Engineers at Duke University have demonstrated a technique that uses microbubbles and ultrasound to help relatively large cancer drugs enter tumor cells and cause them to self-destruct.

Generative AI aids discovery of ISM3830's novel scaffold

Casitas B-lineage lymphoma-b (CBLB) is an E3 ubiquitin–protein ligase that functions as an intracellular checkpoint and master negative regulator of T‑cell and natural killer (NK) cell activation, playing a central role in modulating T-cell activation and immune tolerance, and its inhibition enhances T cells and NK cells function, also provides a strategy for the function restoration of exhausted T cells.

Researchers discover a direct pathway for macrophage cleanup

Macrophages are part of the immune system's frontline; they attack and eat invaders to protect surrounding cells. They, along with other cells, maintain intracellular conditions through macroautophagy, using autophagosomes to help digest broken cell components.

All-atom models reveal novel protein misfolding mechanism

New computer simulations that model every atom of a protein as it folds into its final three-dimensional form support the existence of a recently identified type of protein misfolding.
