We are deeply saddened by the passing of Amos Bairoch (1957–2025), the creator of PROSITE. We wish to dedicate our latest paper, published shortly before his death, to him. He will always be a source of inspiration to us.
Our deepest condolences go out to his family and friends, and to all those who had the privilege of working with him. Rest in peace, Amos. Your work will live on long after you are gone.

Description
A number of eukaryotic ribosomal proteins can be grouped on the basis of sequence similarities. One of these families consists of:
- Mammalian S21 [1].
- Caenorhabditis elegans S21.
- Plants S21.
- Yeast S21 (Ys25) [2].
- Fission yeast S28 [3].
These proteins have 82 to 87 amino acids. As a signature pattern, we selected a highly conserved nonapeptide in the N-terminal part of these proteins.
Last update:November 2005 / Pattern and text revised.
