Abstract: Little is known about the molecular components and interactions of the planar cell polarity pathway that regulate neuronal polarity. This study uses a prkl-1 induced backwards locomotion defect as an array to perform a prkl-1 suppressor screen in C. elegans looking for new components of the planar cell polarity pathway involved in the neuronal polarization of VC4 and VC5. The screen discovered twelve new alleles of vang-1, one new allele of fntb-1 and five new mutations in unknown polarity genes. fntb-1 encodes for the worm ortholog of Farnesyltransferase β-subunit and is important for neuronal polarization. Acting cell and non-cell autonomously, fntb-1 regulates the function and localization of prkl-1 through the recognition of a CAAX motif. Therefore, fntb-1 modifies prkl-1 to regulate the neuronal polarity of VC4 and VC5.
