BTBD7 (BTB Domain Containing 7) is a protein that plays a key role in regulating epithelial-mesenchymal transition (EMT), an essential process in embryonic development, tissue repair, and cancer metastasis. It aids in controlling cell shape and movement by affecting the cell’s cytoskeleton. Dysregulation of BTBD7 is linked to fibrosis and tumour progression, underscoring its importance in tissue remodelling and its potential as a therapeutic target in fibrotic conditions and metastatic cancer.
