It stabilizes a number of different RNA elements and thus is important for subunit structure.

Located at the interface of the 30S and 50S subunits, it traverses the body of the 30S subunit contacting proteins on the other side and probably holding the rRNA structure together. The combined cluster of proteins S8, S12 and S17 appears to hold together the shoulder and platform of the 30S subunit (By similarity). [[http://www.uniprot.org/uniprot/RL23_THET2 RL23_THET2]] One of the early assembly proteins it binds 23S rRNA.
