Disease

TLL1_HUMAN Defects in TLL1 are the cause of atrial septal defect type 6 (ASD6) [MIM:613087. A congenital heart malformation characterized by incomplete closure of the wall between the atria resulting in blood flow from the left to the right atria.[1]

Function

TLL1_HUMAN Protease which processes procollagen C-propeptides, such as chordin, pro-biglycan and pro-lysyl oxidase. Required for the embryonic development. Predominant protease, which in the development, influences dorsal-ventral patterning and skeletogenesis.

Publication Abstract from PubMed

Procollagen C-peptidase, also known as bone morphogenetic protein 1 (BMP-1), is a multidomain, zinc endopeptidase of the astacin M12A family. BMP-1 is the prototype of a small group of proteases that have key roles in extracellular matrix formation and morphogenesis. BMP-1, its splice form mTLD, and the related proteases TLL-1 and TLL-2 are considered as promising drug targets for the treatment of excessive fibrosis and muscle wasting. We report here the crystal structures of the protease domains of human BMP-1 and the closely related Tolloid-like protease 1 (TLL-1). The crystal structures reveal an unexpected conformation of a cysteine-rich loop within the active site, and suggest that a flap movement is required in order to allow substrate binding. On the basis of these substantial differences between the BMP-1 and astacin active sites, a structural basis for their differing substrate specificities is proposed.
