PFAM accession number:PF00687
Interpro abstract (IPR028364):

This entry also matches ribosome biogenesis proteins, such as Cic1, which associates with the proteasome and is required for the degradation of specific substrates [ (PUBMED:11500370) ], and for the synthesis of 60S ribosome subunits [ (PUBMED:14623999) ].

Ribosomal protein L1 is the largest protein from the large ribosomal subunit. The L1 protein contains two domains: 2-layer alpha/beta domain and a 3-layer alpha/beta domain (interrupts the first domain). The two domains cycle between open and closed conformations via a hinge motion. In Escherichia coli, L1 is known to bind to the 23S rRNA. The RNA-binding site of L1 is highly conserved, with both mRNA and rRNA binding the same binding site. Like several other large ribosomal subunit proteins, L1 displays RNA chaperone activity [ (PUBMED:17517772) (PUBMED:15659579) (PUBMED:16330048) (PUBMED:12037305) (PUBMED:10801481) (PUBMED:12514741) ]. It belongs to a family of ribosomal proteins which, on the basis of sequence similarities [ (PUBMED:8635468) (PUBMED:8607874) ], groups:

  • Eubacterial L1
  • Algal and plant chloroplast L1
  • Cyanelle L1
  • Archaebacterial L1
  • Vertebrate L10A
  • Yeast Utp30, Rpl1a, Rpl1b and Mrpl1.
