Abstract

The "A Disintegrin And Metalloproteinase" (ADAM) protein family and the "A Disintegrin-like And Metalloproteinase with ThromboSpondin motifs" (ADAMTS) protein family are two related families of human proteins. The similarities and differences between these two families have been investigated using phylogenetic trees and homology modeling. The phylogenetic analysis indicates that the two families are well differentiated, even when only the common metalloprotease domain is taken into account. Within the ADAM family, several proteins are lacking the binding motif for the catalytic zinc in the active site and thus presumably lack any catalytic activity. These proteins tend to cluster within the ADAM phylogenetic tree and are expressed in specific tissues, suggesting a functional differentiation. The present analysis allows us to propose the following: (i) ADAMTS proteins have a conserved role in the human organism as proteases, with some differentiation in terms of substrate specificity; (ii) ADAM proteins can act as proteases and/or mediators of intermolecular interactions; (iii) proteolytically active ADAMs tend to be more ubiquitously expressed than the inactive ones. © 2005 American Chemical Society.
