UniProt functional annotation for Q9RXK1

UniProt code: Q9RXK1.

Organism: Deinococcus radiodurans (strain ATCC 13939 / DSM 20539 / JCM 16871 / LMG 4051 / NBRC 15346 / NCIMB 9279 / R1 / VKM B-1422).
Taxonomy: Bacteria; Deinococcus-Thermus; Deinococci; Deinococcales; Deinococcaceae; Deinococcus.
 
Function: One of the primary rRNA binding proteins, this protein initially binds near the 5'-end of the 23S rRNA. It is important during the early stages of 50S assembly (By similarity). {ECO:0000250}.
 
Function: Makes multiple contacts with different domains of the 23S rRNA in the assembled 50S subunit.
 
Function: This protein is located close to the polypeptide exit tunnel, and interacts with the modified macrolide azithromycin, which blocks the tunnel.
 
Subunit: Part of the 50S ribosomal subunit. Contacts proteins L15 and L34. {ECO:0000269|PubMed:11677599, ECO:0000269|PubMed:12535524, ECO:0000269|PubMed:12623020, ECO:0000269|PubMed:12665853, ECO:0000269|PubMed:15059283, ECO:0000269|PubMed:15554968}.
Similarity: Belongs to the universal ribosomal protein uL4 family. {ECO:0000305}.
