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 counteracting 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 when scanning or elongating ribosomes are blocked from progressing past the start codon. |

RNF10 monoubiquitinates RPS2/uS5 and RPS3/uS3 on ribosomes stalled in translation; overexpression of RNF10 phenocopies USP10 knockout by increasing 40S subunit degradation. PAR-CLIP showed RNF10 crosslinks to mRNAs, tRNAs, and 18S rRNA, indicating direct recruitment to stalled ribosomes. ZNF598-independent translation initiation and elongation impairment also contributes to RNF10-mediated ubiquitination. |

Mammalian 18S nonfunctional rRNA decay (NRD) proceeds through a GCN2-RNF10-RIOK3 axis: nonfunctional 18S rRNA induces translational arrest at start sites, activating GCN2 (integrated stress response), which limits translation initiation; RNF10-mediated ubiquitination of 40S proteins then promotes 40S ribosomal protein turnover and 18S rRNA decay, with RIOK3 binding ubiquitinated 40S subunits to facilitate 18S rRNA degradation. |

RIOK3 specifically recognizes RNF10-ubiquitylated 40S ribosomes through a unique ubiquitin-interacting motif (visualized by cryo-EM), and mediates progressive 3'-to-5' decay of 18S rRNA in the ubiquitylated 40S subunit. Starvation induces selective depletion of 40S ribosomes via RNF10 ubiquitylation followed by RIOK3-dependent degradation. |

Disruption of 60S biogenesis triggers iRQC activation and 40S decay via RNF10-mediated ubiquitylation of uS3/uS5; depletion of the scanning helicase eIF4A1 impairs 40S ubiquitylation, indicating mRNA engagement is required for iRQC. Amino acid starvation also stimulates iRQC-dependent 40S decay. RIOK3 interacts with ubiquitylated 40S subunits to mediate degradation, and both RNF10 and RIOK3 protein levels increase upon iRQC activation (feedforward mechanism). |

RNF10-mediated monoubiquitination of RPS3/uS3 antagonizes ribosomal half-mer formation by promoting dissociation of 40S subunits from ribosomes stalled during both translation elongation and aberrant initiation. RNF10 protein levels are coupled to 40S subunit abundance: knockdown of RPS proteins leads to proteasomal degradation of RNF10, whereas knockdown of RPL proteins causes accumulation of stalled initiating 40S subunits and increased RNF10 levels. |

RNF10 is a synaptonuclear messenger enriched at excitatory synapses where it associates with the GluN2A subunit of NMDA receptors. Activation of synaptic GluN2A-containing NMDARs and LTP induction cause RNF10 translocation from dendritic segments and spines to the nucleus via importin-dependent long-distance transport. 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 trafficking. Preventing Ser31 phosphorylation decreases spine density, neuronal branching, and CREB signaling; mimicking stable Ser31 phosphorylation has opposite effects. |

RNF10 expression increases upon retinoic acid-induced neuronal differentiation of P19 cells; RNF10 knockdown impairs neuronal differentiation and prevents cell cycle arrest after RA treatment. RNF10 regulates cell cycle exit through upregulation of p21 (but not p27 or p57), and ectopic p21 partially rescues the differentiation defect caused by RNF10 depletion. |

In the context of vascular calcification in chronic kidney disease, nuclear RNF10 negatively regulates Rbpjk expression in VSMCs through a transcriptional (non-ubiquitin-ligase) mechanism. Proteasome inhibition does not impair RNF10's anticalcific activity. Viral Rbpjk overexpression reverses RNF10's protective effects, while Rbpjk knockdown reduces osteogenic markers, defining an RNF10-Rbpjk regulatory axis. |
