PROSITE documentation PDOC00901 [for PROSITE entry PS01171]

Ribosomal protein L21e signature





Description

A number of eukaryotic and archaebacterial ribosomal proteins can be grouped on the basis of sequence similarities. One of these families consists of:

  • Mammalian L21 [1].
  • Entamoeba histolytica L21 [2].
  • Caenorhabditis elegans L21 (C14B9.7).
  • Yeast L21E (URP1) [3].
  • Halobacterium marismortui HL31 [4].

These proteins have 160 (eukaryotes) or 95 (archebacteria) amino-acid residues. As a signature pattern, we selected a conserved region in the central part of these proteins.

April 2006 / Pattern revised.
