Often, for gene transcription to occur, a number of transcription factors must bind to DNA regulatory sequences. This collection of transcription factors, in turn, recruit intermediary proteins such as cofactors that allow efficient recruitment of the preinitiation complex and RNA polymerase.ranscription factors use a variety of mechanisms for the regulation of gene expression. These mechanisms include: 1  stabilize or block the binding of RNA polymerase to DNA. 2  catalyze the acetylation or deacetylation of histone proteins.

It does not make a difference when in the day you take Lexapro; it is just important that you take it at the same time each day consistently.The best time of the day to take it is when you are most likely to remember to take it.   If you are on 20mg, for example, take 10 m â¦ g for a week and then 5mg for a week and then 5mg every other day.     I am not a doctor and you really should talk to YOUR doctor about tapering. Coming off of Lexapro has some pretty nasty side effects for some folks.
