ccTi1594 [mex-5p::GFP::gpr-1::smu-1 3'UTR + Cbr-unc-119(+), III: 680195] III. GFP expression in germline. Transgene rescues unc-119(ed3).

Neomycin resistant. The genomic location of ccTi1594 is with respect to the WEBcel235 assembly.

Deletion that spans exons 1-3 (out of 4) and is presumed to be a null. Under EM, one type of intestinal granule is missing. Missing type is not acidic, and does not stain with nile red. Under DIC, gut is lighter and the granules are not as densely packed.
