THBS3 (Thrombospondin 3): THBS3 is a gene that encodes a protein belonging to the thrombospondin family, which is involved in cell-to-cell and cell-to-matrix communication. It plays a role in tissue remodelling, wound healing, and angiogenesis—the formation of new blood vessels. Dysregulation of THBS3 has been associated with various pathological conditions, including fibrosis and cancer.
