VANGL2 is a core PCP protein. In Drosophila, asymmetric localization of Stbm (the fly VANGL homologue) and Fz to opposite membranes is a hallmark of the establishment of planar cell polarity (reviewed in Maung and Jenny, 2011). In the mouse inner-ear sensory hair cells, VANGL2 is also asymmetrically distributed in the membrane (Montcouquiol et al, 2003, 2006), and this distribution depends on a direct interaction with SCRIB, a peripheral membrane protein with no known role in fly PCP (reviewed in May-Simera and Kelley, 2012). Asymmetric VANGL2 localization in the mouse inner ear also depends on CELSR1, homologue to the Drosophila core PCP protein Flamingo, however a direct interaction between VANGL2 and CELSR1 has not been demonstrated (Montcouquiol et al, 2006).
