alg-1(ap428 [alg-1::Y45F10D.4 3’UTR]) X. alg-1 control strain. ap428 is a CRISPR-engineered allele in which the endogenous alg-1 3'UTR was replaced by the Y45F10D.4 3'UTR. The Y45F10D.4 3'UTR was chosen because it appears to be stably expressed, is commonly used as a control gene in quantitative RT-PCR experiments, and its short 3’UTR lacks ALG-1 binding sites.
