Cleavage at Asp-275 by CASP1 (mature and uncleaved precursor forms) , CASP4 , CASP5 or CASP8 relieves autoinhibition and is sufficient to initiate pyroptosis (PubMed:26375003 , PubMed:29898893 , PubMed:32109412) . Cleavage by CASP1 and CASP4 is not strictly dependent on the consensus cleavage site on GSDMD but depends on an exosite interface on CASP1 that recognizes and binds the Gasdermin-D , C-terminal (GSDMD-CT) part (PubMed:32109412) . Cleavage by CASP8 takes place following inactivation of MAP3K7/TAK1 by Yersinia toxin YopJ (By similarity) . Cleavage at Asp-87 by CASP3 or CAPS7 inactivates the ability to mediate pyroptosis (PubMed:28392147 , PubMed:28045099) .
