Ribosomal protein P0 is the functional equivalent of E.coli protein L10. P0 forms a pentameric complex by interaction with dimers of P1 and P2 (PubMed:3323886). Identified in a IGF2BP1-dependent mRNP granule complex containing untranslated mRNAs (PubMed:17289661). Interacts with APEX1 (PubMed:19188445). Interacts with FMR1 isoform 6 (PubMed:24658146). Localized in cytoplasmic mRNP granules containing untranslated mRNAs (PubMed:19188445, PubMed:17289661). Belongs to the universal ribosomal protein uL10 family.
