Strain contains a set of dual specialized safe harbor transgene landing pads for integration of promoters: one driving mScarlet and rescuing hygromycin resistance upon integration, the other driving mNeonGreen and rescuing the unc phenotype upon integration.

Superficially wild-type. This is the appropriate control strain for FUS disease models HA2846 and HA2847. This control strain contains presumably silent edits inserted by CRISPR editing while creating the FUS disease models in HA2846 and HA2847, and was back-crossed to remove the pha-1 allele used in strain construction.

fust-1(rt256[R446S]) was created by CRISPR editing of arginine codon in C. elegans fust-1 to create FUS disease model for human mutation R524S. This strain also contains additional silent edits (also present in control strain HA2845), and was back-crossed to remove the pha-1 allele used in strain construction. Under normal culture conditions HA2846 animals are superficially wild-type; after stress latent defects are observed.

fust-1(rt257[P447L]) was created by CRISPR editing of proline codon in C. elegans fust-1 to create FUS disease model for human mutation P525L. This strain also contains additional silent edits (also present in control strain HA2845), and was back-crossed to remove the pha-1 allele used in strain construction. Under normal culture conditions HA2847 animals are superficially wild-type; after stress latent defects are observed. Reference: Baskoylu S, et al. bioRxiv 799932; doi: https://doi.org/10.1101/799932
