E3 ubiquitin-protein ligase that catalyzes 'Lys-11'- or 'Lys- 33'-linked polyubiquitin chains, with some preference for 'Lys-33' linkages (PubMed:25752577). E3 ubiquitin-protein ligases accept ubiquitin from an E2 ubiquitin-conjugating enzyme in the form of a thioester and then directly transfers the ubiquitin to targeted substrates (PubMed:23479728, PubMed:31578312). Ubiquitinates SEPTIN4, DIABLO/SMAC and HTRA2 in vitro (PubMed:23479728). Modulates pulmonary inflammation by targeting SOCS2 for ubiquitination and subsequent degradation by the proteasome (PubMed:31578312). {ECO:0000269|PubMed:23479728, ECO:0000269|PubMed:25752577, ECO:0000269|PubMed:31578312}. This is the function of Ensembl gene identifier ENSG00000119682 (AREL1, apoptosis resistant E3 ubiquitin protein ligase 1).
