Protein attributes

Sequence length	178 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at protein level.

General annotation (Comments)

Function	It is located near the subunit interface in the base of the L7/L12 stalk, and near the tRNA binding site of the peptidyltransferase center By similarity. This protein binds to the 23S rRNA, and is important in its secondary structure.
Subunit structure	Part of the 50S ribosomal subunit.
Sequence similarities	Belongs to the ribosomal protein L6P family.
