OX NCBI_TaxID=4522; RN [1] RP NUCLEOTIDE SEQUENCE [LARGE SCALE GENOMIC DNA]. RC STRAIN=cv. Cashel; RA Diekmann K., Hodkinson T.R., van den Bekerom R., Dix P.J., Wolfe K.H., RA Barth S.; RT "Complete chloroplast genome sequence of perennial ryegrass (Lolium RT perenne L.)."; RL Submitted (JUL-2007) to the EMBL/GenBank/DDBJ databases. RN [2] RP NUCLEOTIDE SEQUENCE [GENOMIC DNA]. RA Nadot S., Bajon R., Lejeune B.; RT "The chloroplast gene rps4 as a tool for the study of Poaceae RT phylogeny."; RL Plant Syst. Evol. 191:27-28(1994). CC -!- FUNCTION: One of the primary rRNA binding proteins, it binds CC directly to 16S rRNA where it nucleates assembly of the body of CC the 30S subunit (By similarity). CC -!- FUNCTION: With S5 and S12 plays an important role in translational CC accuracy (By similarity). CC -!- SUBUNIT: Part of the 30S ribosomal subunit. Contacts protein S5. CC The interaction surface between S4 and S5 is involved in control CC of translational fidelity (By similarity). CC -!- SUBCELLULAR LOCATION: Plastid, chloroplast. CC -!- SIMILARITY: Belongs to the ribosomal protein S4P family. CC -!- SIMILARITY: Contains 1 S4 RNA-binding domain.
