== Function ==
[https://www.uniprot.org/uniprot/UB2D2_HUMAN UB2D2_HUMAN] Accepts ubiquitin from the E1 complex and catalyzes its covalent attachment to other proteins. In vitro catalyzes 'Lys-48'-linked polyubiquitination. Mediates the selective degradation of short-lived and abnormal proteins. Functions in the E6/E6-AP-induced ubiquitination of p53/TP53. Mediates ubiquitination of PEX5 and autoubiquitination of STUB1 and TRAF6. Involved in the signal-induced conjugation and subsequent degradation of NFKBIA, FBXW2-mediated GCM1 ubiquitination and degradation, MDM2-dependent degradation of p53/TP53 and the activation of MAVS in the mitochondria by DDX58/RIG-I in response to viral infection. Essential for viral activation of IRF3.<ref>PMID:10329681</ref> <ref>PMID:15280377</ref> <ref>PMID:18042044</ref> <ref>PMID:18703417</ref> <ref>PMID:18359941</ref> <ref>PMID:19854139</ref> <ref>PMID:20403326</ref> <ref>PMID:20061386</ref>
