Model shows different modes of Parkin activation.

The cis activation model uses the binding of pUbl in the same molecule, thus resulting in the displacement of RING2 (1). The trans-activation model uses the binding of pUbl of fully activated Parkin (phospho-Parkin complex with pUb) with partially activated Parkin (WT-Parkin and pUb complex), thus resulting in the displacement of RING2 in trans (2). Recruitment and activation of Parkin isoforms lacking Ubl (Isoform 10) or RING2 domain (Isoform 5), thus complementing each other using the trans-activation model (3). Catalytic cysteine on RING2 is highlighted.
