Ribosomal protein L14 signature


Ribosomal protein L14 is one of the proteins from the large ribosomal subunit. In eubacteria, L14 is known to bind directly to the 23S rRNA. It belongs to a family of ribosomal proteins which, on the basis of sequence similarities [1], groups:

  • Eubacterial L14.
  • Algal and plant chloroplast L14.
  • Cyanelle L14.
  • Archaebacterial L14.
  • Yeast L17A.
  • Mammalian L23.
  • Caenorhabditis elegans L23 (B0336.10).
  • Higher eukaryotes mitochondrial L14.
  • Yeast mitochondrial Yml38 (gene MRPL38).

L14 is a protein of 119 to 137 amino-acid residues. As a signature pattern, we selected a conserved region located in the C-terminal half of these proteins.
