Might have an extraribosomal function in reinitiation of translation of ETTIN and MONOPTEROS genes that are involved in the auxin-mediated gynoecium patterning (PubMed:16227452). Essential in leaf polarity establishment, probably having a role for translation in leaf dorsoventral patterning to specify leaf adaxial identity (PubMed:18305007). Interacts with REIL1 AND REIL2 (PubMed:24603461). Component of the large ribosomal subunit (By similarity). Ubiquitous. Abnormal leaf patterning, with the abaxial mesophyll features appearing in the adaxial mesophyll domain. Belongs to the eukaryotic ribosomal protein eL24 family.
