"Transcriptional activation" refers to the process of turning on the activity or expression of a gene in the cell. It is a mechanism that activates the gene to produce its corresponding protein or RNA molecule. Full definition
To demonstrate the capabilities of SpDamID in the current study, the authors analyzed Notch - mediated transcriptional activation in mouse kidney progenitor cells (mK4 cells). (sciencedaily.com)
In the medium - term, CRISPR technology will be useful not for killing DNA but for real DNA editing: for gene replacement, or to modify specific amino acids and provide new functionalities to existent genes, and for transcriptional activation of repression of genes, modulating their expression levels.» (wheat.org)
IRE1 is a serine / threonine protein kinase and endoribonuclease that signals transcriptional activation by initiating a novel splicing reaction on the mRNA encoding the transcription factor XBP1. (sbpdiscovery.org)
