RNF213 encodes a 591-kDa cytosolic protein possessing a Walker motif (ATPase) and a RING finger domain that exhibit ATPase and ubiquitin ligase activities, respectively. Knockdown of RNF213 in zebrafish caused irregular wall formation in trunk arteries and abnormal sprouting vessels, establishing a role in vascular development. |

Mysterin/RNF213 contains two tandem AAA+ ATPase modules and forms a large ring-shaped oligomeric complex. Fluorescence correlation spectroscopy and biochemical evaluation showed that RNF213 dynamically changes its oligomeric state through ATP/ADP binding and hydrolysis cycles, consistent with a mechanical AAA+ ATPase mechanism. |

RNF213 is upregulated by IFN-β through STAT signaling in endothelial cells and mediates antiangiogenic activity of IFN-β. The R4810K variant decreases ATPase activity (similar to a Walker B motif stabilizing mutation WEQ) and stabilizes oligomers, causing antiangiogenic activity even without IFN-β stimulation. EC-specific Rnf213 R4757K transgenic mice showed suppressed cerebral angiogenesis under hypoxia, while wild-type overexpression did not. |

RING domain mutations from MMD patients reduce RNF213 ubiquitin ligase activity (using Ubc13/Uev1A as E2, generating K63-linked polyubiquitin chains in vitro). In full-length overexpression experiments in HEK293T cells, these mutations conversely enhanced NF-κB activation and caspase-3-mediated apoptosis in an AAA+ domain-dependent manner, suggesting NF-κB/apoptosis activities are negatively regulated by RNF213 E3 ligase activity. |

RNF213 ubiquitylates the lipid A moiety of bacterial lipopolysaccharide (LPS) on cytosol-invading Salmonella, forming a ubiquitin coat. This requires the dynein-like core of RNF213 but not its RING domain; instead, an RZ finger mediates ubiquitylation. RNF213 is essential for recruitment of LUBAC (which adds M1-linked chains) and ubiquitin-dependent autophagy receptors, restricting Salmonella proliferation. |

UBC13 (UBE2N) is an E2 ubiquitin-conjugating enzyme for RNF213, identified by yeast two-hybrid screening with the RNF213 RING domain as bait, and confirmed by co-immunoprecipitation in vivo. RNF213 autoubiquitinates via K63-linked chains (not K48) in a UBC13-dependent manner. UBC13 knockdown and ubiquitination-dead RNF213 mutants reduced HUVEC cell migration and invasion, indicating the RNF213-UBC13 axis contributes to angiogenic activity. |

RNF213 uses E2-conjugating enzymes UBE2D2 and UBE2L3 for distinct ubiquitylation events: RNF213-UBE2D2 catalyzes K6 (and K48) poly-ubiquitylation in vitro, while RNF213-UBE2L3 catalyzes K6-, K11-, and K48-linked chains. MMD-associated SNPs encode proteins with decreased E3 activity. The most frequent MMD allele (p.R4810K) acts as a dominant-negative mutant that globally decreases ubiquitylation but does not affect ATPase activity. |

IFN-γ-inducible RNF213 translocates to Toxoplasma gondii parasitophorous vacuoles (PVs) and facilitates PV ubiquitylation (linear and K63-linked) in human cells independently of LUBAC. RNF213 is required for IFN-γ-mediated growth restriction of T. gondii. The ATPase domain is required for RNF213 recruitment to the PVM, while loss of a critical histidine in the RZ finger abolishes ubiquitylation; both are needed for parasite growth restriction. |

Genome-wide CRISPR screen identified RNF213 as necessary for IFN-γ-mediated restriction of T. gondii. The ATPase domain is required for RNF213 recruitment to the parasitophorous vacuole membrane (PVM), while the RZ finger domain is required for ubiquitination. Both are required for parasite growth restriction. RNF213-mediated restriction is independent of ATG5 (non-canonical autophagy). RNF213 overexpression in naive (non-IFN-γ stimulated) cells is sufficient to restrict T. gondii growth. |

Morpholino-mediated knockdown caused significant reduction in fast myofibrils and immature projection of primary motoneurons, leading to severe motor deficits.
