ADAM7 (ADAM metallopeptidase domain 7) is a non-catalytic member of the disintegrin-metalloproteinase family with diverse biological functions. In reproductive biology, ADAM7 is essential for male fertility, being specifically expressed in the epididymis where it maintains epithelial cell morphology and supports sperm development 1. The protein can be delivered to cells via epididymosomes, suggesting a role in sperm maturation 2. ADAM7 also functions in cellular adhesion through its disintegrin domain, which is recognized by lymphocyte integrins α4β1, α4β7, and α9β1, indicating roles in immune cell interactions 3. In pathological contexts, ADAM7 promotes trophoblast cell proliferation and invasion through p38MAPK signaling, potentially contributing to placental development 4. The gene is frequently mutated in melanoma, where mutations affect cell adhesion to extracellular matrix proteins and may influence tumor progression 5. Additionally, ADAM7 expression is dysregulated in male infertility and shows strong interactions with regulatory miRNAs (miR-34a and miR-449), suggesting its utility as a biomarker for reproductive disorders 6. Recent studies also implicate ADAM7 as a potential therapeutic target in end-stage renal disease-associated sarcopenia 7.
