Active metalloproteinase with gelatinolytic and collagenolytic activity. Plays a role in the wound healing process. Mediates both heterotypic intraepithelial cell/T-cell interactions and homotypic T-cell aggregation. Inhibits beta-1 integrin-mediated cell adhesion and migration of airway smooth muscle cells. Suppresses cell motility on or towards fibronectin possibly by driving alpha-v/beta-1 integrin (ITAGV-ITGB1) cell surface expression via ERK1/2 inactivation. Cleaves E-cadherin in response to growth factor deprivation. Plays a role in glomerular cell migration. Plays a role in pathological neovascularization. May play a role in cartilage remodeling. May be proteolytically processed, during sperm epididymal maturation and the acrosome reaction. May play a role in sperm-egg binding through its disintegrin domain. {ECO:0000269|PubMed:12091380, ECO:0000269|PubMed:15358598, ECO:0000269|PubMed:15818704, ECO:0000269|PubMed:17416588, ECO:0000269|PubMed:17575078, ECO:0000269|PubMed:18387333, ECO:0000269|PubMed:18434311}. This is the function of ADAM15 (ADAM metallopeptidase domain 15, ENSG00000143537).
