Superficially wild-type. This is the appropriate control strain for FUS disease models HA2846 and HA2847.

Description: 20% maternal effect sterility on average, RNAi insensitivity, MEG-3 does not form cytoplasmic gradient. meg-3(ax4503) is an in-frame deletion in the endogenous meg-3 locus removing amino acids (1-544); MEG-3 does not form a cytoplasmic gradient but does still form granules in early embryos and co-localizes with PGL-3.

20% Maternal effect sterility on average, embryonic P granule defect, RNAi insensitivity. Engineered mutations in the endogenous meg-3 locus disrupt the binding and localization of PGL proteins to P granules in the early embryo while MEG-3 itself is still forms an asymmetric cytoplasmic gradient and granules.
