Gene activation refers to the process where genes are turned on in response to changes in neural activity, leading to the expression of specific genes in the brain. This activation can be observed in both birds and humans through various methods such as motor- and sensory-driven gene expression and imaging techniques like PET and MRI.
Gene activation and inactivation are complicated, multistep, and tightly controlled molecular mechanisms. Increasingly it is being recognized that the promoter CpG island of a silenced gene is occupied by a polycomb group complex that modulates chromatin remodeling.
Gene activation occurs when a stimulation, normally a physical-biological element, stimulates the natural proteins that are part of the genetic material of cells and is thus turning the genes “on” that were “off” and is therefore considered to be gene-regulating.
Because the active, DNA-binding form of the protein serves to turn genes off, this mode of gene regulation is called negative control, and the gene regulatory proteins that function in this way are called transcriptional repressors or gene repressor proteins.
Transcriptional activators are required to turn on the expression of genes in a eukaryotic cell. Activators bound to the enhancer can facilitate either the recruitment of RNA polymerase II to the promoter or its elongation.
20 Δεκ 2023 · Gene activation refers to the process by which a gene is turned “on” or activated, meaning that the gene’s DNA is transcribed into RNA, and ultimately, translated into protein. This process is tightly regulated and involves a multitude of factors that work together in a highly orchestrated manner.
