Many biological functions are regulated by the switching on and off of mechanisms triggered by the matching of a keyhole ...

Protein arginylation is an evolutionarily conserved post‐translational modification whereby arginine is covalently attached to specific residues on target proteins. Mediated principally by the enzyme ...

Extracellular vesicles (EVs) are tiny biological bubbles that carry nucleic acids and proteins between cells, playing an essential role in tissue repair, neuroprotection and immune health. By ...

Researchers have discovered a previously unknown cell-protecting function of a protein, which could open new avenues for treating age-related diseases and lead to healthier aging overall. McMaster ...

In addition to exporting materials out of the nucleus, the protein, called Exportin-1 (also called Xpo1 or Crm1), seems to play a role in promoting gene transcription, the process that creates RNA ...

Mitochondria possess their own mRNA translation system, mediated by specialized mitoribosomes. Dysregulation of mitochondrial translation disrupts metabolic homeostasis and is linked to various ...

A new study led by Rice University's Pernilla Wittung-Stafshede has revealed that protein clumps, or plaques that clog the brain, associated with Parkinson's disease are not merely waste; they can ...

A paper published in Cell highlights how researchers have leveraged AI-based computational protein design to create a novel synthetic ligand that activates the Notch signaling pathway, a key driver in ...

Neurons have a "hibernation mode." Scientists discover how brain cells use RNA tentacles to lock their protein factories together to survive when energy is low.

Claudia Rückert, Ph.D., is an assistant professor in the Department of Biochemistry & Molecular Biology at the University of Nevada, Reno. She received her bachelor’s degree in biology and master's ...

UCLA scientists have characterized the structure and function of a key survival protein in breast cancer cells that helps explain how these tumors resist environmental stress and thrive in acidic, low ...
