What is the function of complement proteins?

What is the complement system made up of?
Over 30 proteins and protein fragments make up the complement system, including serum proteins, and cell membrane receptors. They account for about 10% of the globulin fraction of blood serum. Three biochemical pathways activate the complement system: the classical complement pathway, the alternative complement pathway, and the lectin pathway.

These are covered by nine central components of the cascade (C1 to C9), multiple activation products (such as C3a and C3b), regulators and inhibitors (e.g. Factor H and C4BP), proteases and newly assembled enzymes (e.g. C4b2a and Factor B), or effector molecule receptors (such as C3aR and C5aR) (Tables 1–3).
What are the 3 main functions of the complement system?
At the basic level the broad functions of the complement system can be split into three areas: (1) the activation of inflammation; (2) the opsonization (labeling) of pathogens and cells for clearance/destruction; (3) the direct killing of target cells/microbes by lysis.

What makes up the complement system?
The complement system consists of a number of small proteins that are synthesized by the liver, and circulate in the blood as inactive precursors. When stimulated by one of several triggers, proteases in the system cleave specific proteins to release cytokines and initiate an amplifying cascade of further cleavages.

Are complement proteins cytokines?
Activation of inflammation – Several peptides produced by proteolytic cleavage of complement proteins bind to vascular endothelial cells and lymphocytes. These cells then produce cytokines which stimulate inflammation and enhances responses to foreign antigens.
What is C3a and C5a?
C3a and C5a, the small (approximately 10KDa) cleavage fragments released by complement activation, are potent mediators of inflammation. They are anaphylatoxins and act as cell activators with nanomolar affinity, exerting their functions through binding to specific receptors (C3aR and C5aR or C5L2 respectively).

What is the Complement System?
A complement system can be explained with an analogy of an army trying to protect and defend a specific territory from an enemy. Once an enemy is spotted within the territory, the army buckles up and eliminates the enemy. Likewise, a series of proteins in the human body circulates in the blood and tissues, ready to eliminate an invading pathogen.
Complement System Function
A complement system works together with the other immune system components such as antibodies to quickly destroy and eliminate an invading pathogen, such as bacteria or a parasite. Once a pathogen has been spotted in the body, the complement system gets activated and eliminates this pathogen through:
Alternative Pathway
This pathway is activated when the complement protein gets into contact and binds to the cell surface of a pathogen. The complement protein involved in binding on the pathogen's surface is C3b. The components of this pathway are C3, Factor D, Factor B, and Properdin.
What is complement in plasma?
Complement was discovered many years ago as a heat-labile component of normal plasma that augments the opsonization of bacteria by antibodies and allows antibodies to kill some bacteria. This activity was said to ‘complement’ the antibacterial activity of antibody, hence the name. Although first discovered as an effector arm ...

Summary
The complement system, also known as complement cascade, is a part of the immune system that enhances (complements) the ability of antibodies and phagocytic cells to clear microbes and damaged cells from an organism, promote inflammation, and attack the pathogen's cell membrane. It is part of the innate immune system, which is not adaptable and does not change during an individ…
History
In 1888, George Nuttall found that sheep blood serum had mild killing activity against the bacterium that causes anthrax. The killing activity disappeared when he heated the blood. In 1891, Hans Ernst August Buchner, noting the same property of blood in his experiments, named the killing property "alexin", which means "to ward off" in Greek. By 1894, several laboratories had demonstrated that serum from guinea pigs that had recovered from cholera killed the cholera bacterium in vitro. He…
Functions
Complement triggers the following immune functions:
1. Membrane attack – by rupturing the cell wall of bacteria. (Classical Complement Pathway)
2. Phagocytosis – by opsonizing antigens. C3b has most important opsonizing activity. (Alternative Complement Pathway)
Overview
Most of the proteins and glycoproteins that constitute the complement system are synthesized by hepatocytes. But significant amounts are also produced by tissue macrophages, blood monocytes, and epithelial cells of the genitourinary system and gastrointestinal tract. The three pathways of activation all generate homologous variants of the protease C3-convertase. The classical complemen…
Activation of complements by antigen-associated antibody
In the classical pathway, C1 binds with its C1q subunits to Fc fragments (made of CH2 region) of IgG or IgM, which has formed a complex with antigens. C4b and C3b are also able to bind to antigen-associated IgG or IgM, to its Fc portion.
Such immunoglobulin-mediated binding of the complement may be interpreted as that the complement uses the ability of the immunoglobulin to detect and bind to non-self antigens as it…
Regulation
The complement system has the potential to be extremely damaging to host tissues, meaning its activation must be tightly regulated. The complement system is regulated by complement control proteins, which are present at a higher concentration in the blood plasma than the complement proteins themselves. Some complement control proteins are present on the membranes of self-cells preventing them from being targeted by complement. One example is CD59, also known as …
Role in disease
It is thought that the complement system might play a role in many diseases with an immune component, such as Barraquer–Simons syndrome, asthma, lupus erythematosus, glomerulonephritis, various forms of arthritis, autoimmune heart disease, multiple sclerosis, inflammatory bowel disease, paroxysmal nocturnal hemoglobinuria, atypical hemolytic uremic syndrome and ischemia-reperfusion injuries, and rejection of transplanted organs.
Modulation by infections
Recent research has suggested that the complement system is manipulated during HIV/AIDS, in a way that further damages the body.
