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.
