General annotation (Comments)

Function	This is 1 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. In the 70S ribosome it contacts protein S13 of the 30S subunit (forming bridge B1b) connecting the head of the 30S subunit to the top of the 50S subunit. The bridge itself contacts the P site tRNA and is implicated in movement during ribosome translocation. Also contacts the P site tRNA independently of the intersubunit bridge; the 5S rRNA and some of its associated proteins might help stabilize positioning of ribosome-bound tRNAs By similarity.
Subunit structure	Forms a bridge to the 30S subunit in the 70S ribosome, contacting protein S13; this bridge is straddled by the 5S rRNA. Contacts the P site tRNA By similarity. Part of the 50S ribosomal subunit; part of the 5S rRNA/L5/L18/L25 (TL5) subcomplex.
Sequence similarities	Belongs to the ribosomal protein L5P family.
