function:E3 ubiquitin-protein ligase which accepts ubiquitin from E2 ubiquitin-conjugating enzymes UBE2L3 and UBE2L6 in the form of a thioester and then directly transfers the ubiquitin to targeted substrates, such as SNCAIP or CASR. Specifically ubiquitinates pathogenic SOD1 variants, which leads to their proteasomal degradation and to neuronal protection.,pathway:Protein modification; protein ubiquitination.,PTM:Phosphorylated upon DNA damage, probably by ATM or ATR.,similarity:Belongs to the RBR family. RNF19 subfamily.,similarity:Contains 1 IBR-type zinc finger.,similarity:Contains 2 RING-type zinc fingers.,subcellular location:Present in the hyaline inclusion bodies specifically found in motor neurons from amyotrophic lateral sclerosis patients. Present in the Lewy bodies specifically found in neurons from Parkinson disease patients.,subunit:Interacts with UBE2L3 and UBE2L6. Interacts with transcription factor Sp1. Interacts with VCP, CASR, SNCAIP and with some SOD1 variants which cause amyotrophic lateral sclerosis, but not with wild-type SOD1.,tissue specificity:Widely expressed, with highest levels in heart. Ubiquitously expressed in the central nervous system.,
