PROSITE documentation PDOC00764 [for PROSITE entry PS00996]

Ribosomal protein S21e signature





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.
