CC -!- FUNCTION: Controls the classical pathway of complement activation. It
CC binds as a cofactor to C3b/C4b inactivator (C3bINA), which then
CC hydrolyzes the complement fragment C4b. It also accelerates the
CC degradation of the C4bC2a complex (C3 convertase) by dissociating the
CC complement fragment C2a. Alpha chain binds C4b. It interacts also with
CC anticoagulant protein S and with serum amyloid P component.
CC -!- SUBUNIT: Disulfide-linked complex of alpha and beta chains of 3
CC possible sorts: a 570 kDa complex of 7 alpha chains and 1 beta chain, a
CC 530 kDa homoheptamer of alpha chains or a 500 kDa complex of 6 alpha
CC chains and 1 beta chain. The central body of the alpha chain homomer
CC supports tentacles, each with the binding site for C4b at the end.
CC {ECO:0000269|PubMed:16330538}.
CC -!- SUBUNIT: (Microbial infection) Interacts with Staphylococcus aureus
CC protein SdrE; this interaction inhibits complement-mediated bacterial
CC opsonization. {ECO:0000269|PubMed:24600566}.
CC -!- INTERACTION:
CC P04003; PRO_0000023526 [P02741]: CRP; NbExp=4; IntAct=EBI-978348, EBI-22033103;
CC P04003; P13050: arp4; Xeno; NbExp=5; IntAct=EBI-978348, EBI-978341;
CC -!- SUBCELLULAR LOCATION: Secreted.
CC -!- TISSUE SPECIFICITY: Chylomicrons in the plasma.
CC -!- CAUTION: It is uncertain whether Met-1 or Met-17 is the initiator.
CC {ECO:0000305}.
