Forms part of the ribosomal stalk which helps the ribosome interact 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 (Probable). Belongs to the universal ribosomal protein uL11 family.
