Depositor Comments

Zinc fingers are cloned in between the unique XbaI and BamHI sites. This results in an expression vector which encodes a ZFN with the OPEN zinc finger array fused to the mutant FokI nuclease domain.

pMLM290 is identical to pST1374 except that it harbors two mutations in the FokI nuclease domain (E490K and I538K; aka the “+” mutation see Miller et al., Nat. Biotech 2007, PMID 17603475) which confers heterodimeric behavior on these domains.
