Indirect processing of PDGFRα and direct cleavage of ADAMTSL1 by MMP10. A, Domain structure of PDGFRα with annotated cleavage site in the extracellular domain, time-dependent abundance profile of the generated neo-N terminus, and characterization of processing by incubation of recombinant proteins and immunoblot analysis of MMP10-incubated secretomes. Lack of cleavage of recombinant PDGFRα by MMP10 indicates indirect cleavage in MMP10-incubated cell supernatants. B, Domain structure of ADAMTSL1 (isoform 1) with annotated cleavage site in an extended loop between thrombospondin domains (TS) 2 and 3, time-dependent abundance profile of the generated neo-N terminus, and validation of processing by incubation of recombinant proteins. Detection of MMP10-generated fragments with expected molecular weights by silver stain and immunoblot analysis identified ADAMTSL1 as a direct MMP10 substrate.
