The met repressor may serve as a useful model for such systems.

Jim had told him to shave and put on more beard repressor.

The beard repressor he used had worn off at least twenty-four hours ago.

Now, when either chemical was present, the repressor was expressed.

He decided against using beard repressor and went over to the closet to pull on a uniform.

So, he added, "difficult problems like the lac repressor tend to be put aside."

That repressor, in turn, blocks production of the output.

In his latter capacity, he was regarded by critics as a repressor of political dissent.

In panel (e) the complementation test for repressor is shown.

They are usually constantly expressed so the cell always has a supply of repressor molecules on hand.

Then there's the repressor protein that turns genes off.

The inducer can remove this repressor, turning genes back on.

The met repressor protein was overexpressed and purified as before.

Blimp1, a general repressor of transcription is also expressed.

AP-4 has been shown to act both as a repressor and an activator for different target genes.

This would increase the affinity of repressor for O.

From there, molecular biologists became obsessed with the lactose repressor.

The regulator gene is always 'on', and synthesizes repressor at a very low rate.

They then linked their reporter gene to a promoter that was bound by the repressor.

Hsp90, by itself and/or associated with multichaperone complexes, is a major repressor of this gene.

Studies in mouse suggest that this protein may function as a transcriptional repressor.

Gli2 was also found to be a stronger activator while Gli3 was a strong repressor.

The gene is expressed because an inducer binds to the repressor.

The repressor is active in the absence of lactose.

"I'm sorry, Sir," says this repressor of my rights, currently masquerading as the girl behind the counter.
