Function |
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. {ECO:0000269|PubMed:2809217}.

Subcellular Location |
Cytoplasmic granule lumen {ECO:0000269|PubMed:2809217}. Secreted {ECO:0000269|PubMed:2809217}. Cell membrane {ECO:0000269|PubMed:2809217}; Multi-pass membrane protein {ECO:0000269|PubMed:2809217}. Endosome lumen {ECO:0000250}. Note=Stored in cytoplasmic granules of cytolytic T-lymphocytes and secreted into the cleft between T-lymphocyte and target cell. Inserts into the cell membrane of target cells and forms pores. Membrane insertion and pore formation requires a major conformation change. May be taken up via endocytosis involving clathrin-coated vesicles and accumulate in a first time in large early endosomes (By similarity). {ECO:0000250}.

Tissue Specificity |
Detected in large granular lymphocytes and lymphokine-activated killer cells. {ECO:0000269|PubMed:2809217}.
