Depositor Comments

This plasmid encodes a zinc finger array targeting half of a target sequence in the zebrafish gene cdkn1a(p21) (see below). Please note that this plasmid does NOT contain the cdkn1a(p21) sequence.

Users must order the complementary plasmid cdkn1a(p21)_R (OZ556) [Addgene plasmid 28081] 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 (Addgene plasmid 21872), pMLM292 (Addgene plasmid 21873), pMLM800 (Addgene plasmid 27202) and pMLM802 (Addgene plasmid 27203).

This zinc finger array was tested for binding activity to the sequence 5'-GAGTGAACG-3' in a bacterial two hybrid assay, and resulted in 14.32 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 [email protected] and acknowledge NIH grant number R01 GM088040 in the publication.
