Probable ligand for integrin in the brain. This is a non catalytic metalloprotease-like protein. Can bind to LGI1 and LGI4. Highly expressed in the brain. Weakly detected in the heart, liver and testis. A conserved motif [AVN[ED]CD] within the disintegrin-like domain could be involved in the binding to the integrin receptor. The precursor is cleaved by a furin endopeptidase.
