pIGLET: Safe harbor landing sites for reproducible and efficient transgenesis in zebrafish.

ABSTRACT: Standard methods for transgenesis in zebrafish depend on random transgene integration into the genome followed by resource-intensive screening and validation. Targeted vector integration into validated genomic loci using phiC31 integrase-based attP/attB recombination has transformed mouse and Drosophila transgenesis. However, while the phiC31 system functions in zebrafish, validated loci carrying attP-based landing or safe harbor sites suitable for universal transgenesis applications in zebrafish have not been established. Here, using CRISPR-Cas9, we converted two well-validated single insertion Tol2-based zebrafish transgenes with long-standing genetic stability into two attP landing sites, called phiC31 Integrase Genomic Loci Engineered for Tr
