Function
function
Pore-forming protein involved in both innate and adaptive immunity. Plays a central role in antigen cross-presentation in dendritic cells by forming a pore in antigen-containing compartments, thereby promoting delivery of antigens for cross-presentation. Also involved in innate immune response following bacterial infection; shows antibacterial activity against a wide spectrum of Gram-positive, Gram-negative and acid-fast bacteria. Reduces the viability of the intracytosolic pathogen L.monocytogenes by inhibiting acidification of the phagocytic vacuole of host cells which restricts bacterial translocation from the vacuole to the cytosol. Required for the antibacterial activity of reactive oxygen species and nitric oxide.
Pore-forming protein that plays a central role in antigen cross-presentation in dendritic cells by mediating delivery of antigens for cross-presentation. Dendritic cells bridge innate and adaptive immunity by capturing exogenous antigens on MHC class-I molecules and presenting them to naive CD8+ T-cells. Acts by forming a pore in antigen-containing compartments, promoting the release of antigens into the cytosol, enabling generation of MHCI:peptide complexes and T-cell priming.
