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.

Study shows how TAF1 regulates ferroptosis in cancer cells

Ferroptosis has become a promising area in cancer research because it may provide a way to target tumor cells that evade other better-known forms of programmed cell death, such as apoptosis and necroptosis.

Natural compound obakulactone shows therapeutic potential for rheumatoid arthritis

A new study published in Engineering reveals that obakulactone (OL), a natural tetracyclic triterpenoid isolated from Phellodendri cortex, exerts a therapeutic effect on rheumatoid arthritis (RA) by promoting the degradation of acyl coenzyme A thioesterase 1 (ACOT1) via the ubiquitin‒proteasome pathway and restoring the homeostasis of unsaturated fatty acids.

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.
