UBE2D1-dependent E3 ubiquitin-protein ligase that mediates the ubiquitination of NEFL and of phosphorylated BCL2L11. Plays a neuroprotective function. May play a role in neuronal rapid ischemic tolerance. Plays a role in antiviral immunity and limits New World arenavirus infection independently of its ubiquitin ligase activity (PubMed:24068738). {ECO:0000250|UniProtKB:Q9ESN6, ECO:0000269|PubMed:24068738}. This is the function of ENSG00000109654 (TRIM2, tripartite motif containing 2).
