Homeobox protein Meis2 is a protein that in humans is encoded by the MEIS2 gene. [5] [6]This gene encodes a homeobox protein belonging to the TALE ('three amino acid loop extension') family of homeodomain-containing proteins.

Activation of gene transcription is a complex system of signal cascades and recruitment of necessary components such as RNA polymerase and transcription factors. IEGs are often the first responders to regulatory signals with many reaching peak expression within 30 minutes after stimuli compared to 2–4 hours in the case of delayed primary ...
MEF2, Myocyte Enhancer Factor 2, is a transcription factor with four specific numbers such as MEF2A, B, C, and D. Each MEF2 gene is located on a specific chromosome. MEF2 is known to be involved in the development and the looping of the heart (Chen) MEF2 is necessary for myocyte differentiation and gene activation (Black).

In animal cells, CAK phosphorylates the Cdk subunit only after cyclin binding, and so the two steps in Cdk activation are usually ordered as shown here, with cyclin binding occurring first. Budding yeast contains a different version of CAK that can phosphorylate the Cdk even in the absence of cyclin, and so the two activation steps can occur in ...
Transvection can lead to either gene activation or repression. [1] It can also occur between nonallelic regions of the genome as well as regions of the genome that are not transcribed. The first observation of mitotic (i.e. non-meiotic) chromosome pairing was discovered via microscopy in 1908 by Nettie Stevens. [2]
