Forms part of the ribosomal stalk, playing a central role in the interaction of the ribosome with GTP-bound translation factors. Part of the 50S ribosomal subunit. Forms part of the ribosomal stalk which helps the ribosome interact with GTP-bound translation factors. Forms a heptameric L10(L12)2(L12)2(L12)2 complex, where L10 forms an elongated spine to which 3 L12 dimers bind in a sequential fashion. The N-terminus is blocked. Isolated L10(L12)6. Belongs to the universal ribosomal protein uL10 family. Note that in PubMed:11154066 it was found that the N-terminus is blocked, whereas the mass determined in PubMed:16287167 suggests that the initiator methionine is removed. No extra mass for a blocking group was found.
