DORFIN Proteins and Enzymes

Dorfin is an E3 ubiquitin ligase which mediates ubiquitination of cellular proteins. Dorfin contains two RING-finger motifs and an IBR (in between RING fingers) motif. Dorfin interacts with UBE2L3/UBCH7 and UBE2E2/UBCH8, but not other ubiquitin-conjugating enzymes. Dorfin is of interest in Parkinson's Disease, as it binds and ubiquitylates synphilin 1 (SNCAIP - interacts with alpha synuclein) in neurons. Furthermore, Dorfin expression is increased in Lewy bodies, the characteristic neuronal ...
