RL PLoS ONE 7:E34991-E34991(2012).
CC -!- FUNCTION: Recombinant, non-modified protein stimulates secretion of
CC cytokines (TNF-alpha, IL-6 and IL-12p40) by mouse macrophage cell lines
CC in a TLR2-dependent fashion, which leads to increased host innate
CC immunity responses against the bacterium (PubMed:22174456). Serves as a
CC strong human and mouse antigen T cell antigen during M.tuberculosis
CC infection, inducing strong IFN-gamma expression (PubMed:22567094).
CC {ECO:0000269|PubMed:22174456, ECO:0000269|PubMed:22567094}.
CC -!- SUBUNIT: Interacts with host TLR2 (tested in mouse) (PubMed:22174456).
CC {ECO:0000269|PubMed:22174456}.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000255|PROSITE-
CC ProRule:PRU00303, ECO:0000305|PubMed:22567094,
CC ECO:0000305|PubMed:8633206}; Lipid-anchor {ECO:0000255|PROSITE-
CC ProRule:PRU00303}. Secreted, cell wall {ECO:0000305|PubMed:22567094}.
CC Secreted {ECO:0000250|UniProtKB:P0CAX7}.
CC -!- INDUCTION: Highly expressed and immunogenic during infection of mice
CC with live bacteria (at protein level). {ECO:0000269|PubMed:8633206}.
CC -!- PTM: O-glycosylated. Contains 0-3 mannose residues attached to residues
CC 48-49 in various configurations; the dominant glycoform is Thr-
CC 48(Man)/Thr-49(Man2) with an unusual Man(1->3)Man linkage, but
CC Thr48(Man3)/Thr49(Man0) through to Thr48(Man0/)Thr49(Man3) are also
CC seen (By similarity). {ECO:0000250|UniProtKB:P0CAX7}.
CC -!- BIOTECHNOLOGY: Could be used in vaccine production; both recombinant
CC protein and DNA vaccines stimulate antigen-specific T cell responses in
CC mice (PubMed:22567094). {ECO:0000269|PubMed:22567094}.
