ADAMTS6 is a secreted zinc metalloendopeptidase that belongs to the ADAMTS family of extracellular matrix-associated proteases 1. The protein is processed by furin cleavage to become catalytically active and functions in extracellular matrix organization 2. ADAMTS6 plays a complex role in cellular adhesion and communication by negatively regulating focal adhesions and heparan sulfate-rich interfaces, contrasting with its homolog ADAMTS10 2. In cardiovascular physiology, ADAMTS6 missense variants are associated with cardiac conduction abnormalities, with functional studies demonstrating its role in connexin 43 gap junction expression essential for myocardial conduction 34. The protein exhibits tissue-specific and context-dependent effects in cancer. In breast cancer, ADAMTS6 functions as a tumor suppressor by inhibiting cell migration, invasion, and tumorigenesis through modulation of the ERK signaling pathway, with high expression correlating with improved disease-free survival 5. Conversely, in gastric carcinoma, ADAMTS6 promotes tumor growth and angiogenesis, with high expression associated with poor prognosis 6. Additionally, genetic variants in ADAMTS6 have been associated with lumbar disc herniation susceptibility 7, and its promoter methylation patterns may serve as diagnostic markers in non-small-cell lung cancer 8.
