What Does IEG Stand For?

IEG stands for Immediate Early Gene

IEG, or Immediate Early Gene, refers to a category of genes that are rapidly activated in response to various stimuli, such as stress or growth factors, before any significant changes in protein synthesis occur. These genes play a crucial role in cellular response mechanisms and are often involved in processes such as neuronal signaling, cell differentiation, and proliferation. Their expression typically occurs within minutes of stimulation, making them key indicators of immediate cellular activity.
