Ribosomal protein S12 is one of the proteins from the small ribosomal subunit.
In Escherichia coli, S12 is known to be involved in the translation initiation
step. It is a very basic protein of 120 to 150 amino-acid residues. S12
belongs to a family of ribosomal proteins which, on the basis of sequence
similarities , groups:
Algal and plant chloroplast S12.
Protozoa and plant mitochondrial S12.
Drosophila mitochondrial protein tko (Technical KnockOut).
As a signature pattern, we selected the best conserved regions in these
proteins, located in the center of each sequence.
