IRX3

IRX3, also known as Iroquois homeobox protein 3, is a transcription factor encoded by the IRX3 gene. It is a member of the Iroquois homeobox (IRX) gene family, which play crucial roles in embryonic development and tissue patterning. The IRX3 protein is characterized by a homeodomain, a conserved DNA-binding motif.

In humans, the IRX3 gene is located on chromosome 16. IRX3 is known to be involved in the development of various organs and tissues, including the brain, kidney, and limbs. It acts by regulating the expression of other genes, thereby influencing cell differentiation, proliferation, and migration.

Research has indicated that IRX3 plays a significant role in adipogenesis, the process of fat cell formation. Dysregulation of IRX3 has been implicated in metabolic disorders such as obesity and type 2 diabetes, suggesting its importance in energy homeostasis. Furthermore, its role in developmental processes has led to investigations into its involvement in certain cancers, though this area requires further study. The precise molecular mechanisms by which IRX3 exerts its functions are still being actively investigated.
