This region is known as the enhancer region. Studies have suggested that thyroid hormone (T3) controls Sox2 expression via the enhancer region. The expression of TRα1 (thyroid hormone receptor) is increased in proliferating and migrating neural stem cells.
An enhancer localized in a DNA region distant from the promoter of a gene can have a very large effect on gene expression, with some genes undergoing up to 100-fold increased expression due to an activated enhancer. [32] Enhancers are regions of the genome that are major gene-regulatory elements. Enhancers control cell-type-specific gene ...
If you’re stuck on today’s Wordle answer, we’re here to help—but beware of spoilers for Wordle 1259 ahead. Let's start with a few hints.
The Ig heavy chain locus super-enhancer is a very large (25kb) cis-regulatory region, including multiple enhancers and controlling several major modifications of the locus (notably somatic hypermutation, class-switch recombination and locus suicide recombination).
Enhanceosomes are formed in special cases when these activators cooperatively bind together along the enhancer sequence to create a distinct three-dimensional structure. Each enhanceosome is unique towards its specific enhancer. This assembly is facilitated by energetically favorable protein: protein and protein: DNA interactions. Therefore ...

Enhancers are DNA sequences found in 5′ flanking regions of eukaryotic genes that affect transcription. If a transcription factor binds to an enhancer in a 5′ flanking region, the DNA strand bends in a way that the transcription factor that is bound to the enhancer can also bind the promoter of a gene.
MyoD, also known as myoblast determination protein 1, [5] is a protein in animals that plays a major role in regulating muscle differentiation.MyoD, which was discovered in the laboratory of Harold M. Weintraub, [6] belongs to a family of proteins known as myogenic regulatory factors (MRFs). [7]
