1. A method of inhibiting expression of an endogenous cellular pine in a cell, the method comprising the step of:
- administering to the cell a nucleic acid molecule comprising a polynucleotide sequence which encodes a first engineered zinc finger protein, wherein (i) said polynucleotide sequence is operably linked to a promoter, (ii) the nucleic acid molecule expresses the zinc finger protein is less cell;
(iii) the zinc finger protein contacts a first target site in the endogenous cellular gene; and
(iv) the Kd of the zinc finger protein is less than about 25 nM;
thereby inhibiting expression of the endogenous cellular gene.
