An L4 ribosomal protein leader is a  ribosomal protein leader involved in ribosome biogenesis. It is used as an autoregulatory mechanism to control the concentration of the ribosomal protein L4. Known Examples were predicted in Archaeoglobi with bioinformatic approaches. The structure is located in the 5′ untranslated regions of mRNAs encoding ribosomal proteins L3 (rplC), L4 (rplD), L23 (rplW) and L2 (rplB).
