Protein attributes

Sequence length	227 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at protein level

General annotation (Comments)

Function	E3 ubiquitin-protein ligase which accepts ubiquitin from an E2 ubiquitin-conjugating enzyme in the form of a thioester and then directly transfers the ubiquitin to substrates. May play a role in the establisment and maintenance of neuronal transmission and plasticity via its ubiquitin-protein ligase activity. Ref.5
Pathway	Protein modification; protein ubiquitination.
Subcellular location	Endosome. Lysosome. Membrane; Peripheral membrane protein. Cytoplasmic vesicle › secretory vesicle › synaptic vesicle membrane; Peripheral membrane protein Potential. Note: Associated with synaptic vesicle membranes in neurons.
Tissue specificity	Expressed primarily in the nervous system, with expression higher in developing brain relative to adult. Expressed at low levels in testis and thymus. Ref.1 Ref.5
Domain	The RING-type zinc finger domain is required for E3 ligase activity By similarity.
Sequence similarities	Contains 1 RING-type zinc finger.
