Description
Evgenia Deryusheva and co-authors published a research paper in 2024 on a small protein part that grabs RNA, and what its spread across life says about how cells evolved. The part, called the S1 domain, sits in proteins of bacteria, archaea, and complex cells, often repeated several times in one protein. The team mined a global protein database for every case.
Bacterial proteins held up to eight copies, and complex-cell proteins up to fifteen, while archaea held just one. Some chloroplast proteins carried S1 forms that match those of the bacteria those cell parts descend from. The same held for a protein in mitochondria. The pattern backs the view that these cell parts began as free bacteria.
