SNAI1 snail family transcriptional repressor 1 [ (human)]
The Drosophila embryonic protein snail is a zinc finger transcriptional repressor which downregulates the expression of ectodermal genes within the mesoderm. The nuclear protein encoded by this gene is structurally similar to the Drosophila snail protein, and is also thought to be critical for mesoderm formation in the developing embryo. At least two variants of a similar processed pseudogene ...

Are the genes for transcriptional factors close to their targets in the genome? Transcriptional factors (activators and repressors) are proteins which regulate transcription. Being proteins, they themselves are also m...
> Is the gene coding for the transcriptional factor always present next to (or close to) the transcription unit? Not necessarily. You can find several counter-examples. Even for prokaryotes this is not necessarily true. The genes regulated by a common factor are called regulons and though the target...

Why does the pET- expression vector contain a LacI gene additionally to the one in the genome? The pET plasmid is used for protein expression with T7 promotor in expression strains, such as _E.coli_ BL21(DE3) It cont...
The easiest way around this problem is to put a _lacI_ (or _lacI Q_) gene on the expression plasmid so that repressor levels are commensurate with the

Constitutive mutation in operator gene If a constitutive mutation happens in the operator of an inducible operon, does that mean that repressors won't be able to bind them ? Or does it mean that even if repressors are...
Reason: Mutation of the repressor, so its not present, doesn't bind or binds only with very low affinity for the operon. 1. The repressor can not bind. Reason: The binding site for the repressor is mutated. See this Website or this Website for more information.
