CC -!- FUNCTION: Mediates the entry of L.monocytogenes into normally non-
CC phagocytic mammalian host cells (PubMed:19900460). Its host receptor is
CC hepatocyte growth factor receptor (HGF receptor, a tyrosine kinase,
CC MET) which is tyrosine-phosphorylated in response to InlB. Downstream
CC targets MAPK1/MAPK3 (Erk1/2) and AKT are phosphorylated in response to
CC InlB, which also causes cell colony scattering (PubMed:19900460,
CC PubMed:21345802, PubMed:22887347, PubMed:27789707). Complement
CC component 1 Q subcomponent-binding protein (gC1q-R, C1QBP) has been
CC suggested to also act an InlB receptor, but this is less certain.
CC Stimulation of Tyr-phosphorylation of MET by InlB is potentiated by the
CC InlB GW domains and glycosaminoglycans such as heparin (By similarity).
CC {ECO:0000250|UniProtKB:P0DQD3, ECO:0000269|PubMed:19900460,
CC ECO:0000269|PubMed:21345802, ECO:0000269|PubMed:22887347,
CC ECO:0000269|PubMed:27789707}.
CC -!- SUBUNIT: Interacts via its LRR repeats plus the Ig-like region with the
CC extracellular portion (residues 25-741) of its receptor MET; MET can
CC bind HGF, its endogenous ligand, and InlB simultaneously
CC (PubMed:17662939). Probably forms a dimer upon interaction with host
CC MET, which subsequently allows dimerization of the host MET and
CC subsequent host signaling; dimerization probably occurs via the convex
CC surface of InlB (PubMed:19900460) (Probable). Prevention of
CC dimerization does not block interaction with MET but prevents
CC downstream action (PubMed:19900460). {ECO:0000269|PubMed:17662939,
CC ECO:0000269|PubMed:19900460, ECO:0000305|PubMed:22887347}.
CC -!- INTERACTION:

CC P0DQD2; P08581: MET; Xeno; NbExp=4; IntAct=EBI-1379295, EBI-1039152;
CC -!- SUBCELLULAR LOCATION: Secreted {ECO:0000250|UniProtKB:P0DQD3}.
CC Cytoplasm {ECO:0000269|PubMed:11929538}. Cell membrane
CC {ECO:0000269|PubMed:11929538}. Note=Approximately half the protein is
CC secreted. Cell surface association is mediated by the GW domains and
CC can occur when protein is added externally; externally added protein
CC confers invasion competence. Protein is partially buried in the cell
CC membrane; it binds non-covalently to lipoteichoic acid (LTA) on the
CC bacterial membrane, and can be released from the surface by LTA.
CC {ECO:0000250|UniProtKB:P0DQD3}.
CC -!- DOMAIN: The N-terminus (36-79) resembles a truncated EF hand, the LRR
CC region (80-240) has a curved form, while residues 241-321 form an Ig-
CC like region; the whole region forms a curved tube (PubMed:11575932,
CC PubMed:17662939, PubMed:19900460). The LRR domain alone (31-241) binds
CC mammalian MET and stimulates its Tyr-phosphorylation; the LRR plus Ig-
CC like region (36-321) are required for receptor dimerization; adding the
CC B-repeat allows the protein to scatter host cell colonies, and the GW
CC domains, especially GW2 and GW3, potentiate MET activation
CC (PubMed:17662939, PubMed:21345802). The cap, LRR and Ig-like regions
CC all interact with residues 25-656 of host MET (the Sema, PSI and Ig1
CC domains) via the interior (concave surface) of the curved tube
CC (PubMed:17662939). Dimerizes via the exterior (convex surface) of the
CC curved tube which probably induces host receptor dimerization;
CC preventing dimerization prevents host downstream signaling
CC (PubMed:19900460) (Probable). The B repeat region crystallizes in a
CC SUMO-like fold. The B repeat region interacts synergistically with N-
CC terminus of InlB, conferring on it the ability to stimulate cell
CC motility; the B repeat does not bind to MET (PubMed:21345802). Deletion
CC of the B-repeat (exact residues are not given) slightly decreased
CC protein activity in host; the authors suggest the B-repeat probably
CC contributes to homodimerization rather than binding another host cell
CC receptor (PubMed:27789707). {ECO:0000269|PubMed:11575932,
CC ECO:0000269|PubMed:17662939, ECO:0000269|PubMed:19900460,
CC ECO:0000269|PubMed:21345802, ECO:0000269|PubMed:27789707,
CC ECO:0000305|PubMed:22887347}.
CC -!- DISRUPTION PHENOTYPE: Deletion of inlB alone decreases host cell entry;
CC the reduction varies from 99% to 37% depending on the cell line tested.
CC {ECO:0000269|PubMed:11929538}.
CC -!- SIMILARITY: Belongs to the internalin family. {ECO:0000305}.
