Model of SGK1 transcription repression by TALE-TF constructs. TALE-TF binds to and unbinds from the GRE of SGK1 with rate constants and
competitive to endogenous GR. If TALE-TF is bound, it prevents gene activation by competitive inhibition of GR DNA binding, and the gene assumes a blocked state (left shade) in addition to the ‘off’- and ‘on’-states of the two-state model of gene transcription (right shade).

: rate constant of SGK1 deactivation,
: transcription rate constant of SGK1,
: degradation rate constant of SGK1. Cartoons illustrate the different states of the extended two-state model.
