Predicted to enable several functions, including transcription coactivator binding activity; ubiquitin ligase inhibitor activity; and ubiquitin protein ligase binding activity. Predicted to be a structural constituent of ribosome. Predicted to be involved in several processes, including cellular response to actinomycin D; negative regulation of nitrogen compound metabolic process; and protein stabilization. Located in ribosome. Part of cytosolic large ribosomal subunit. Is active in postsynaptic density. Orthologous to human RPL23 (ribosomal protein L23).
