UniProt functional annotation for P14123

UniProt code: P14123.

Organism: Haloarcula marismortui (strain ATCC 43049 / DSM 3752 / JCM 8966 / VKM B-1809) (Halobacterium marismortui).
Taxonomy: Archaea; Euryarchaeota; Halobacteria; Halobacteriales; Halobacteriaceae; Haloarcula.
Function: This is one of 5 proteins that mediate the attachment of the 5S rRNA onto the large ribosomal subunit, where it forms part of the central protuberance and stabilizes the orientation of adjacent RNA domains.
Subunit: Part of the 50S ribosomal subunit. Interacts with proteins L5 and L21e, and attaches the 5S rRNA to the 23S rRNA. Has been cross-linked to L21e. {ECO:0000269|PubMed:12150912, ECO:0000269|PubMed:12860128}.
Similarity: Belongs to the ribosomal protein L18P family. {ECO:0000305}.
