Purified human complement component C3. The third component of complement is a centrally important constituent of both the alternative and classical pathways. Upon secretion, pro-C3 undergoes a site specific proteolytic cleavage to yield circulating C3, a protein containing two disulfide bonded subunits (Alpha 115 kD and Beta 75 kD).

C3 is the most abundant complement protein within serum. C3 is a 190 kDa protein, composed of two glycoprotein chains associated through disulphide bonds. Complement C3/C4 Complement (C3/C4) are proteins that are part of the immune system. Measuring complement involved a simple blood test that measures the levels of C3 and C4 in the blood. Measuring complement levels is typically done in autoimmune diseases that affect the levels of complement. C3 and C4 are the most frequently assayed complement proteins, along with total complement. Circulating C3 is synthesized in the liver and comprises 70% of the complement system, but cells in other tissues can also produce C3. C3 is an essential activating protein in the classic and alternate complement cascades.

Complement protein c3

Measurement of complement proteins can be used to monitor treatment results in patients with autoimmune diseases. Lupus erythematosus can cause a C3 level below normal, while rheumatoid arthritis may cause it to rise in the blood but fall in the joint fluid. Tests that measure specific complement proteins, including C3 and C4, are typically reported in milligrams per deciliter (mg/dL). The following are typical complement readings for people age 16 and 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.

Activating proteins C4, C9 and C1q, and regulatory proteins FH and C1-inh were produced constitutively by the four cell lines. C3, C6 and FB were mainly

Most of the proteins are normally inactive, but in response to the recognition of molecular components of microorganisms they become sequentially activated in an enzyme cascade – the activation of one protein enzymatically cleaves and activates the next protein in the cascade. The complement system is made up of a collection of proteins found in the bloodstream and is comprised of nine major complement proteins; complement C3 is one of them. The complement system is a crucial component of the cellular immune system because it kills unwanted bacteria and initiates inflammation.

27 Sep 2005 The mammalian complement system is a phylogenetically ancient cascade system that has a major role in innate and adaptive immunity.

These proteins are part of your complement system. This is an important part of your immune system. It helps kill bacteria and viruses that cause disease. C3 protein is the most important and abundant protein in the complement system. C3 is the most abundant complement protein within serum.
