Outline of Final Research Achievements |
We proposed that the biological and functional significances for the multiple copies of ribosomal stalk protein lie in the efficient assembly of the stalk proteins into the ribosomal particles and the enhancement of the translation rate related to the interaction with GTPase translational factors. Furthermore, we revealed that the C-terminal domain of the stalk protein is a crucial structural element, although L11 (eL12) also acts in coordinated manner, for kingdom-dependent specificity of the ribosome-GTPase translational factor interaction.
