Scientists Discover Over 1,700 'Dark' Proteins Hidden in Human Cells

Researchers identified 1,785 previously overlooked microproteins encoded by non-canonical regions of human DNA.

The team combined large-scale genomic screening with proteomics to confirm these tiny protein-like molecules.

One newly found microprotein was linked to cancer cell growth and survival, highlighting possible medical relevance.

The study strengthens the case that the human “dark genome” can produce functional proteins once thought to be noncoding.
