granzyme-mediated apoptotic signaling pathway http://wiki.geneontology.org/index.php/Apoptosis_Curation_Manual#Other_children_of_apoptotic_signaling_pathway induction of apoptosis by granzyme GO:0008626 The series of molecular signals induced by granzymes which triggers the apoptotic death of a cell. The pathway starts with reception of a granzyme signal, and ends when the execution phase of apoptosis is triggered. Granzymes are serine proteases that are secreted by cytotoxic T cells and natural killer cells to induce apoptosis in target cells. apoptotic signaling pathway in response to granzyme biological_process apoptotic signaling pathway granzyme-mediated programmed cell death signaling pathway
