Plays a key role in secretory granule-dependent cell death, and in defense against virus-infected or neoplastic cells. Can insert into the membrane of target cells in its calcium-bound form, oligomerize and form large pores. Promotes cytolysis and apoptosis of target cells by facilitating the uptake of cytotoxic granzymes.
Specificity
Natural and recombinant Mouse Perforin-1
Subcellular Location
Cytoplasmic granule lumen Secreted Cell membrane Multi-pass membrane protein Endosome lumen Stored in cytoplasmic granules of cytolytic T-lymphocytes and secreted into the cleft between T-lymphocyte and target cell. May be taken up via endocytosis involving clathrin-coated vesicles and accumulate in a first time in large early endosomes (By similarity). Inserts into the cell membrane of target cells and forms pores. Membrane insertion and pore formation requires a major conformation change.
