ITIH3 (Inter-Alpha-Trypsin Inhibitor Heavy Chain 3): ITIH3 is a protein belonging to the inter-alpha-trypsin inhibitor family, which is involved in stabilizing the extracellular matrix and regulating inflammation. It contributes to tissue repair and safeguards against protease-induced tissue damage. Dysregulation of ITIH3 has been linked to cancer progression and inflammatory disorders, underscoring its importance in tissue homeostasis and the immune response.
