• PubMed Abstract: 
  

Ribosomal protein S7, a crucial RNA-binding component of the ribosome, is one of two proteins that initiates assembly of the 30S ribosomal subunit. It is required for proper folding of a large 3' domain of 16S ribosomal RNA. S7 regulates its own synthesis by binding to its own mRNA. This ability of S7 to bind both messenger and ribosomal RNAs makes determination of its mode of RNA recognition particularly interesting.
