Knocking down the function of two Arf GEFs, EFA-6 and M02B7.5, which we name BRIS-1 for its homologs BRAG/IQSEC/Schizo, was able to enhance the
grp-1 A/PVM phenotype, but did not induce a phenotype in animals that were wild type for
grp-1. sing
efa-6 and
bris-1 mutations, we confirmed this enhancer effect in the
grp-1 mutant.
