Protein attributes

Sequence length	122 AA.
Sequence status	Complete.
Protein existence	Inferred from homology

General annotation (Comments)

Function	This is one of the proteins that binds and probably mediates the attachment of the 5S RNA into the large ribosomal subunit, where it forms part of the central protuberance By similarity. HAMAP-Rule MF_01337
Subunit structure	Part of the 50S ribosomal subunit; part of the 5S rRNA/L5/L18/L25 subcomplex. Contacts the 5S and 23S rRNAs By similarity.
Sequence similarities	Belongs to the ribosomal protein L18P family.
