Is located at the subunit interface close to the decoding center. Binds mRNA and the E site tRNA blocking its exit path in the ribosome. This blockage implies that this section of the ribosome must be able to move to release the deacetylated tRNA.[HAMAP-Rule:MF_00480_B] [[http://www.uniprot.org/uniprot/RL1_THETH RL1_THETH]] The L1 stalk is quite mobile in the ribosome, and is involved in E site tRNA release (By similarity).
