spinqualitylabelsall models Ribosomal protein S12 (aqua) complex with 16S RRNA helix 44 (grey), 23S RRNA helix 69 (green) and 23S RRNA SRL (pink) (PDB entry 1qzc) Show:Asymmetric Unit Biological Assembly Drag the structure with the mouse to rotate   Export Animated Image   Print3D Ribosomal protein S12 (RPS12) is one of the 21 proteins which belong to the 30S small subunit of the bacterial ribosome or the 30 proteins which belong to the 40S small subunit of the eukaryotic ribosome. It is involved in the translation initiation step.
