Predicted to enable serine-type endopeptidase activity. Predicted to be involved in several processes, including granzyme-mediated programmed cell death signaling pathway; natural killer cell mediated cytotoxicity; and pyroptosis. Predicted to act upstream of or within cytolysis. Predicted to be located in cytolytic granule. Predicted to be active in cytoplasm and intracellular membrane-bounded organelle. Is expressed in extraembryonic component; placenta; spongiotrophoblast; and trophoblast giant cell. Orthologous to human GZMB (granzyme B). [provided by Alliance of Genome Resources, Apr 2022]
