"RNAi of
bar-1, a b-catenin that binds the b-catenin binding domain of POP-1 (Korswagen et al., 2000; Natarajan et al., 2001), does not give a Sys phenotype; nor does a
bar-1 null mutant. However, RNAi of
wrm-1, a second b-catenin homologue that weakly binds full length POP-1 (Korswagen et al., 2000; Natarajan et al., 2001; Rocheleau et al., 1999), gave a 100% penetrant Sys phenotype in both males and hermaphrodites (Table 4)."
