This plasmid encodes a zinc finger array targeting half of a target sequence in the zebrafish gene SDC3. Please note that this plasmid does NOT contain the SDC3 sequence.
Users must order the complementary plasmid SDC3_L (OZ595) [Addgene plasmid 35235] in order to create a zinc finger nuclease (ZFN) pair to introduce targeted mutations into this specific zebrafish gene.
Users will also need to clone the zinc finger (ZF) insert of this plasmid into a zinc finger nuclease (ZFN) vector to express a FOKI fusion product. Examples of possible ZFN expression vectors that can be used are: pST1374 (Addgene plasmid 13426), pMLM290/292 (Addgene plasmids 21872 & 21873), pMLM800/802 (Addgene plasmids 27202 & 27203).
The difference between pMLM800/802 and pMLM290/292 is the length of the “spacer” sequence in the full ZFN target site. If the spacer is 7 bp, scientists should use pMLM800/802. If the spacer is 5 or 6 bps, scientists should use pMLM290/292.
pMLM290/292 is identical to pST1374 except that it harbors two mutations in the FokI nuclease domain (Q486E, I499L; aka the “-“ mutation see Miller et al., Nat. Biotech 2007, PMID 17603475) which confers heterodimeric behavior on these domains
This zinc finger array was tested for binding activity to the sequence 5'-GAGGTAGAG-3' in a bacterial two hybrid assay, and resulted in 7.47 fold activation. However, this array has not yet been tested for activity as a zinc finger nuclease (i.e. for its ability to induce mutations at the intended locus).
Scientists using this zinc finger array in a publication should notify zebrafishzfs@zincfingers.org and acknowledge NIH grant number R01 GM088040 in the publication.
