    The protein

    Catalyzed reaction/ biological activity

  • silences translation by binding to the L14 protein of the large ribosomal subunit and, as a consequence, impairs subunit joining [Pubmed|22829778]

    • Protein family

  • Iojap/RsfS family (single member, according to UniProt)

    • Structure

  • [PDB|2O5A] (from B. halodurans, 65% identity)

    • [SW|Interactions]

  • [protein|2BE91EEB70A1961D3BBE0603648E64E86CD0B708|RplN]-[protein|B9D5E9B566D28423232C1A28C966CDEA0E5A6B78|RsfS] [Pubmed|22829778], the interaction serves to silence [SW|translation] [Pubmed|22829778]

    • Additional information

  • the protein is enriched in 45S assembly intermediates that accumulate upon depletion of [protein|54CD247926F7FABE4ACE85EB7021B62500B47260|RbgA] [Pubmed|23700310]
