PRICKLE1 is a conserved PCP protein with a localization pattern opposite to that of DVL. PRICKLE1 is recruited to the PARD6A:ppDVL2:SMURF complex through its interaction with DVL and is subsequently ubiquitinated by the E3 ligase activity of SMURF (Narimatsu et al, 2009; Jenny et al, 2005). This leads to localized degradation of PRICKLE1, contributing to its asymmetrical localization (Narimatsu et al, 2009). Note that in this reaction the interaction between PRICKLE1 and DVL is not shown.
