This entry represents a group of plant proteins, including protein SOSEKI1-5 from Arabidopsis thaliana and Physcomitrium patens. SOK1-5 integrate apical-basal and radial organismal axes to localise to polar cell edges and contain a DIX oligomerization domain that resembles that in the animal Dishevelled polarity regulator [1-4].
