EGR1

EGR1 (Early Growth Response 1) is a protein that in humans is encoded by the EGR1 gene. It is also known as Zif268 (zinc finger protein 224), NGFI-A (nerve growth factor-induced protein A), and Krox-24, among other names. EGR1 is a transcription factor with three zinc finger domains that bind to DNA and function in the regulation of cellular growth and differentiation.

Function

EGR1 is a transcription factor that is activated in response to growth factors and stress. It is involved in a variety of biological processes, including cell proliferation, differentiation, apoptosis, and neoplastic transformation. EGR1 can also stimulate expression of target genes, which can influence the growth and development of many types of cells in the body.

Clinical significance

Alterations in EGR1 expression have been associated with various diseases, including cancer, schizophrenia, Alzheimer's disease, and ischemic injury. In cancer, EGR1 can function as a tumor suppressor or an oncogene, depending on the context. In neurological disorders like schizophrenia and Alzheimer's, changes in EGR1 expression may contribute to disease pathology.

Research

Research on EGR1 has focused on its role in cell growth and differentiation, as well as its potential as a therapeutic target in cancer and neurological disorders. Studies have also investigated the regulation of EGR1 expression and its interaction with other proteins and genes.
