CC -!- FUNCTION: A cholesterol-dependent toxin that causes cytolysis by
CC forming pores in cholesterol-containing host membranes. After binding
CC to target membranes, the protein undergoes a major conformation change,
CC leading to its insertion in the host membrane and formation of an
CC oligomeric pore complex. Cholesterol is required for binding to host
CC membranes, membrane insertion and pore formation; cholesterol binding
CC is mediated by a Thr-Leu pair in the C-terminus. Can be reversibly
CC inactivated by oxidation. {ECO:0000269|PubMed:15851031,
CC ECO:0000269|PubMed:20145114, ECO:0000269|PubMed:26333773,
CC ECO:0000269|PubMed:28323617, ECO:0000269|PubMed:9445384}.
CC -!- ACTIVITY REGULATION: Erythrocytes hemolysis is inhibited by
CC cholesterol. {ECO:0000269|PubMed:26333773}.
CC -!- SUBUNIT: Elongated monomers align along their lengths, indicating
CC intersubunit contacts and suggesting the prepore structure
CC (PubMed:15851031, PubMed:26333773, PubMed:26403197, PubMed:27796097,
CC PubMed:28323617). Modeling based on cryo-EM shows a homooligomeric pore
CC complex containing 38-44 subunits; when inserted in the host membrane
CC (Probable). The size of isolated pores is detergent-dependent; in
CC amphipol A8-35 homogenous rings form with 42 subunits
CC (PubMed:28323617). {ECO:0000269|PubMed:15851031,
CC ECO:0000269|PubMed:26333773, ECO:0000269|PubMed:26403197,
CC ECO:0000269|PubMed:27796097, ECO:0000269|PubMed:28323617,
CC ECO:0000305|PubMed:15851031}.
CC -!- SUBCELLULAR LOCATION: Secreted {ECO:0000250|UniProtKB:P0C2J9}. Host
CC cell membrane {ECO:0000269|PubMed:28323617,
CC ECO:0000305|PubMed:15851031}; Multi-pass membrane protein
CC {ECO:0000269|PubMed:28323617}. Note=Secreted as soluble protein by the
CC accessory Sec system (By similarity). It then inserts into the host
CC cell membrane and forms pores formed by transmembrane beta-strands
CC (PubMed:15851031, PubMed:28323617). {ECO:0000250|UniProtKB:P0C2J9,
CC ECO:0000269|PubMed:15851031, ECO:0000269|PubMed:28323617}.
CC -!- DOMAIN: A highly conserved undecapeptide in the C-terminus has residues
CC important for membrane binding and cell lysis (PubMed:9445384). Mature
CC protein has 3 discontinuous domains; D1, D2, D3 followed by C-terminal
CC D4 (PubMed:15851031, PubMed:26333773, PubMed:26403197, PubMed:27796097,
CC PubMed:28323617). The domains rearrange substantially upon membrane
CC insertion, in particular alpha-helices in D3 refold to form the
CC transmembrane beta-strands (PubMed:15851031, PubMed:28323617). The
CC relative position of domain D4 changes, allowing it to interact with
CC host membranes (PubMed:26333773, PubMed:27796097, PubMed:28323617).
CC {ECO:0000269|PubMed:15851031, ECO:0000269|PubMed:26333773,
CC ECO:0000269|PubMed:26403197, ECO:0000269|PubMed:27796097,
CC ECO:0000269|PubMed:28323617, ECO:0000269|PubMed:9445384}.
CC -!- SIMILARITY: Belongs to the cholesterol-dependent cytolysin family.
CC {ECO:0000305}.
