Ddc^em1Gregg

A crRNA (AAUGAAAGCAGAGCUGCUUC) was designed to insert the Ddc-6His-P2A-eGFP-3xNLS construct immediately before the stop codon. Specifically, the construct contained (from 5' to 3') the last 40 bp of Ddc coding sequence c-terminally conjugated with a 6 His epitope tag, P2A self-cleaving peptide sequence, EGFP conjugated with three c-terminal copies of a nuclear localization sequence (3xNLS), stop codon, 37 bp of mutated Ddc 3'-UTR (mUTR) to prevent homology repair between the stop codon and a CRISPR cut site 34 bp downstream (preserving the 3';-splice junction of exon 14), followed by 40 bp of un-mutated Ddc intron 14 sequence.
