RT "RNF217 regulates iron homeostasis through its E3 ubiquitin ligase activity
RT by modulating ferroportin degradation.";
RL Blood 138:689-705(2021).
CC -!- FUNCTION: E3 ubiquitin-protein ligase which accepts ubiquitin from E2
CC ubiquitin-conjugating enzymes in the form of a thioester and then
CC directly transfers the ubiquitin to targeted substrates. Mediates the
CC degradation of the iron exporter ferroportin/SLC40A1 and thus regulates
CC iron homeostasis. {ECO:0000269|PubMed:33895792}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=[E2 ubiquitin-conjugating enzyme]-S-ubiquitinyl-L-cysteine +
CC [acceptor protein]-L-lysine = [E2 ubiquitin-conjugating enzyme]-L-
CC cysteine + [acceptor protein]-N(6)-ubiquitinyl-L-lysine.;
CC EC=2.3.2.31; Evidence={ECO:0000269|PubMed:33895792};
CC -!- PATHWAY: Protein modification; protein ubiquitination.
CC -!- SUBUNIT: Interacts with HAX1. {ECO:0000250|UniProtKB:Q8TC41}.
CC -!- SUBCELLULAR LOCATION: Membrane {ECO:0000305}; Single-pass membrane
CC protein {ECO:0000305}. Cytoplasm {ECO:0000250|UniProtKB:Q8TC41}.
CC -!- DOMAIN: Members of the RBR family are atypical E3 ligases. They
CC interact with the E2 conjugating enzyme UBE2L3 and function like HECT-
CC type E3 enzymes: they bind E2s via the first RING domain, but require
CC an obligate trans-thiolation step during the ubiquitin transfer,
CC requiring a conserved cysteine residue in the second RING domain.
CC {ECO:0000250|UniProtKB:O60260}.
CC -!- DISRUPTION PHENOTYPE: Macrophage-specific knockout mice have increased
CC iron export and altered ferroportin/SLC40A1 degradation.
CC {ECO:0000269|PubMed:33895792}.
CC -!- SIMILARITY: Belongs to the RBR family. RNF217 subfamily. {ECO:0000305}.
