DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).

Cryo-EM imaging of STING protein reveals a new binding source for immune attacks

In new research, UT Southwestern scientists report that imaging a key immunity protein known as STING at near-atomic resolution reveals a previously undiscovered binding location that appears to be crucial for launching immunological attacks.
