Structural highlights
DiseaseUN13D_HUMAN Familial hemophagocytic lymphohistiocytosis. The disease is caused by variants affecting the gene represented in this entry. FunctionUN13D_HUMAN Plays a role in cytotoxic granule exocytosis in lymphocytes. Required for both granule maturation and granule docking and priming at the immunologic synapse. Regulates assembly of recycling and late endosomal structures, leading to the formation of an endosomal exocytic compartment that fuses with perforin-containing granules at the immunologic synapse and licences them for exocytosis. Regulates Ca(2+)-dependent secretory lysosome exocytosis in mast cells.[1] [2] References
