Component of the 40S small ribosomal subunit (PubMed:8706699). Identified in a IGF2BP1-dependent mRNP granule complex containing untranslated mRNAs (PubMed:17289661). Interacts with HNRPD (PubMed:24423872). Interacts with PRMT1; the interaction methylates RPS3 (PubMed:19460357). Interacts with SUMO1; the interaction sumoylates RPS3 (PubMed:21968017). Interacts with UBC9 (PubMed:21968017). Interacts with CDK1; the interaction phosphorylates RPS3 (PubMed:21871177). Interacts with PRKCD; the interaction phosphorylates RPS3 (PubMed:19059439). Interacts with PKB/AKT; the interaction phosphorylates RPS3 (PubMed:20605787). Interacts with E2F1; the interaction occurs in the absence of nerve growth factor and increases transcription of pro-apoptotic proteins BCL2L11/BIM and HRK/Dp5 (PubMed:20605787). Interacts with the base excision repair proteins APEX1 and OGG1; interaction with OGG1 increases OGG1 N-glycosylase activity (PubMed:15518571). Interacts with UNG; the interaction increases the uracil excision activity of UNG1 (PubMed:18973764). Interacts with HSP90; the interaction prevents the ubiquitination and proteasome-dependent degradation of RPS3 and is suppressed by increased ROS levels (PubMed:16314389). Interacts with TOM70; the interaction promotes translocation of RPS3 to the mitochondrion (PubMed:23911537). Interacts (via N-terminus) with RELA (via N-terminus); the interaction enhances the DNA-binding activity of the NF-kappa-B p65-p50 complex (PubMed:18045535). Interacts with NFKBIA; the interaction is direct and may bridge the interaction between RPS3 and RELA (PubMed:24457201). Interacts with IKKB; the interaction phosphorylates RPS3 and enhances its translocation to the nucleus (PubMed:21399639). Interacts (via KH domain) with MDM2 and TP53 (PubMed:19656744). Interacts with TRADD (PubMed:22510408). Interacts (via N-terminus) with E. coli O157:H7 (strain EDL933) nleH1 and nleH2; the interaction with nleH1 inhibits phosphorylation by IKKB, reduces RPS3 nuclear abundance and inhibits transcriptional activation by the NF-kappa-B p65-p50 complex (PubMed:20041225, PubMed:21399639). Interacts with ASCC3 (PubMed:28757607). Identified in a HCV IRES-mediated translation complex, at least composed of EIF3C, IGF2BP1, RPS3 and HCV RNA-replicon (PubMed:19541769). Interacts with CRY1 (By similarity).
