Ribosomal protein S2 signatures





Description

Ribosomal protein S2 is one of the proteins from the small ribosomal subunit. S2 belongs to a family of ribosomal proteins which, on the basis of sequence similarities [1,2], groups:

  • Eubacterial S2.
  • Algal and plant chloroplast S2.
  • Cyanelle S2.
  • Archaebacterial S2.
  • Higher eukaryotes P40 (previously thought to be a laminin receptor).
  • Yeast NAB1.
  • Plant mitochondrial S2.
  • Yeast mitochondrial MRP4.

S2 is a protein of 235 to 394 amino-acid residues. As signature patterns, we selected two conserved regions. One is located in the N-terminal section and the other in the central section.
