RNF10 is the E3 ubiquitin ligase responsible for site-specific monoubiquitylation of 40S ribosomal proteins uS3 (RPS3) and uS5 (RPS2) during ribosome-associated quality control (RQC); USP10 is the opposing deubiquitylase. Prolonged uS3/uS5 ubiquitylation leads to selective 40S (but not 60S) ribosomal protein degradation independent of canonical autophagy. This pathway, termed initiation RQC (iRQC), is triggered by blockade of scanning or elongating ribosomes at the start codon. |

RNF10 is the RING-domain E3 ligase that specifically monoubiquitinates RPS2/uS5 and RPS3/uS3 on ribosomes compromised in translation. RNF10-mediated ubiquitination occurs both downstream of ZNF598-dependent sensing of collided ribosomes and independently upon ZNF598-independent impairment of translation initiation and elongation. PAR-CLIP showed RNF10 crosslinks to mRNAs, tRNAs, and 18S rRNA, indicating physical recruitment to stalled ribosomes. Overexpression of RNF10 increases 40S subunit degradation similarly to USP10 knockout. |

Mammalian 18S nonfunctional rRNA decay (18S NRD) is initiated through the integrated stress response via GCN2. GCN2 activation limits translation initiation, attenuating collisions between scanning 43S preinitiation complexes and stalled nonfunctional ribosomes. RNF10-mediated ubiquitination of 40S ribosomal proteins promotes 18S NRD and 40S ribosomal protein turnover. RIOK3 subsequently binds ubiquitylated 40S subunits to facilitate 18S rRNA decay, establishing a GCN2–RNF10–RIOK3 axis for ribosome surveillance at translation initiation. |

Starvation induces selective depletion of 40S ribosomes through RNF10-mediated ubiquitylation. RIOK3 specifically recognizes ubiquitylated 40S ribosomes via a unique ubiquitin-interacting motif (visualized by cryo-EM). RIOK3 then induces progressive 18S rRNA degradation beginning at the 3' end, as revealed by cryo-EM structures of degradation intermediates. |

RNF10-mediated RPS3/uS3 monoubiquitination antagonizes ribosomal half-mer formation by promoting dissociation of 40S subunits stalled during translation elongation and aberrant translation initiation. RNF10 protein levels are tightly coupled to 40S subunit abundance: knockdown of RPS proteins leads to proteasomal degradation of RNF10, whereas knockdown of RPL proteins increases 40S stalling, elevates RNF10 levels, and enhances RPS3 monoubiquitination. |

Disruption of 60S biogenesis (altered 60S:40S stoichiometry) triggers iRQC activation and RNF10-dependent 40S decay. Depletion of the scanning helicase eIF4A1 impairs 40S ubiquitylation and degradation, indicating that mRNA engagement is required for iRQC. Amino acid starvation also stimulates iRQC-dependent 40S decay. RIOK3 is required for iRQC and interacts with ubiquitylated 40S subunits. RNF10 and RIOK3 protein levels increase upon iRQC activation, establishing a feedforward mechanism. |

RNF10 negatively regulates Rbpjk expression during vascular calcification in a transcriptional (non-ubiquitin ligase) capacity. Nuclear RNF10 expression increases in calcified VSMCs; pharmacological inhibition of the ubiquitin-proteasome system did not impair RNF10's anticalcific activity. Rbpjk overexpression partially reversed the protective effects of RNF10, and Rbpjk knockdown reduced osteogenic marker expression. |

RNF10 functions as a synaptonuclear protein messenger in hippocampal neurons. It associates with the GluN2A subunit of NMDA receptors at excitatory synapses and translocates from dendritic spines to the nucleus in an importin-dependent manner upon activation of synaptic GluN2A-containing NMDARs and LTP induction. RNF10 silencing prevents LTP maintenance and LTP-dependent structural modifications of dendritic spines. |

PKC-dependent phosphorylation of RNF10 at Ser31 is required for RNF10 detachment from the NMDA receptor GluN2A subunit and subsequent nuclear translocation. Preventing Ser31 phosphorylation decreases spine density, neuronal branching, and CREB signaling; mimicking stable Ser31 phosphorylation produces opposite effects. |

RNF10 acts as a transcriptional activator of the myelin-associated glycoprotein (MAG) gene in Schwann cells by binding a cis-acting element 160 bp upstream of the MAG transcription start site. RNF10 overexpression enhanced MAG promoter activity; RNF10 siRNA knockdown reduced MAG mRNA and protein expression and inhibited myelin formation in Schwann cell–DRG neuron co-cultures. |

RNF10 physically binds to the transcription factor MEOX2. In vitro pull-down and co-immunoprecipitation in mammalian cells confirmed the interaction. The minimal MEOX2 binding region maps to amino acids 101–185 (between the HQ-rich domain and homeodomain), while the N-terminal RING finger domain of RNF10 is not required for MEOX2 binding. RNF10 co-expression enhanced MEOX2 activation of the p21WAF1 promoter. |

RNF10 is required for retinoic acid-induced neuronal differentiation and cell cycle exit in P19 embryonic carcinoma cells. Rnf10 knockdown impairs neuronal marker expression and prevents G1 arrest after RA treatment. RNF10 acts via upregulation of the cyclin-dependent kinase inhibitor p21 (but not p27 or p57); ectopic p21 expression partially rescues the differentiation defect caused by Rnf10 depletion. |

In Drosophila, the E3 ligases CNOT4 and RNF10 function upstream of the deubiquitinase OTUD6 to regulate RPS7 ubiquitination and alkylation stress response on the free 40S ribosome. OTUD6 acts on the free 40S (not on 43S/48S or translating ribosomes), and its loss results in RPS7 hyperubiquitination. |
