CC -!- FUNCTION: E3 ubiquitin-protein transferase, which catalyzes CC ubiquitination of target proteins together with ubiquitin-conjugating CC enzyme E2 ubc-18 (By similarity). Acts with ubc-18 to regulate CC pharyngeal development (PubMed:16457801, PubMed:19521497). CC {ECO:0000250|UniProtKB:Q9Y4X5, ECO:0000269|PubMed:16457801, CC ECO:0000269|PubMed:19521497}. 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:0000250|UniProtKB:Q9Y4X5}; CC -!- ACTIVITY REGULATION: Autoinhibited by the ariadne domain, which masks CC the second RING-type zinc finger that contains the active site and CC inhibits the E3 activity. {ECO:0000250|UniProtKB:Q9Y4X5}. CC -!- SUBUNIT: Interacts with ubiquitin-conjugating enzyme E2 ubc-18. CC {ECO:0000269|PubMed:16457801}. CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000269|PubMed:16457801}. Cytoplasm CC {ECO:0000269|PubMed:16457801}. CC -!- DEVELOPMENTAL STAGE: Expression is dynamic during early embryonic CC development, with ubiquitous somatic expression occurring between the CC 50- and 200-cell stage (PubMed:16457801). By the late proliferative CC phase of embryogenesis, expression is reduced, but maintained at high CC levels in muscle precursors (PubMed:16457801). Later in embryogenesis, CC moderate expression occurs in the lateral ectoderm (PubMed:16457801). CC Pharyngeal expression is very low at both the comma and 1.5-fold CC embryonic stages (PubMed:16457801). Expression is highest in muscle and CC neuronal cells in larvae and adults, including many of the amphid CC neurons that are proximal to the posterior bulb of the pharynx CC (PubMed:16457801). Consistent expression in cells of the somatic gonad CC including distal tip, sheath, and spermathecal cells, as well as in CC vulval cells undergoing morphogenesis (PubMed:16457801). Neuronal CC expression in the midbody includes the CAN, HSN, and ALM cells; neurons CC of the ventral and dorsal cords; and a number of posterior deirid CC neurons (PubMed:16457801). Expressed in all pairs of coelomocytes CC (PubMed:16457801). {ECO:0000269|PubMed:16457801}. CC -!- DOMAIN: Members of the RBR family are atypical E3 ligases. They CC interact with an E2 conjugating enzyme and function like HECT-type E3 CC enzymes: they bind E2s via the first RING-type zinc finger, but require CC an obligate trans-thiolation step during the ubiquitin transfer, CC requiring a conserved active site Cys residue in the second RING-type CC zinc finger. The active site probably forms a thioester intermediate CC with ubiquitin taken from the active-site cysteine of the E2 before CC ultimately transferring it to a Lys residue on the substrate. CC {ECO:0000250|UniProtKB:Q9Y4X5}. CC -!- DISRUPTION PHENOTYPE: RNAi-mediated knockdown on a pha-1 or on a lin- CC 35;ubc-18 mutant background produces a high percentage of animals with CC the Pun (pharyngeal unattached) phenotype, whereby the pharynx fails to CC elongate and form an attachment to the anterior alimentary opening or CC buccal cavity. {ECO:0000269|PubMed:16457801}. CC -!- SIMILARITY: Belongs to the RBR family. Ariadne subfamily. CC {ECO:0000305}.
