IEGs are involved in a wide range of cellular processes, including:
Cell proliferation: IEGs can promote or inhibit cell division in response to growth signals. Cell differentiation: IEGs help in the specialization of cells into different types during development. Apoptosis: Some IEGs are involved in programmed cell death, which is crucial for maintaining tissue homeostasis. Synaptic plasticity: In the nervous system, IEGs play a role in the strengthening or weakening of synapses, which is essential for learning and memory.
