C-reactive protein (CRP) is an annular (ring-shaped) pentameric protein found in blood plasma, whose circulating concentrations rise in response to inflammation. It is an acute-phase protein of hepatic origin that increases following interleukin-6 secretion by macrophages and T cells .
One such protein, C-reactive protein (CRP) was originally identified as binding to the phosphocholine attachment site of capsular polysaccharide (C-polysaccharide) from Streptococcus pneumoniae. CRP in blood has a half life of less than a day, compared with 4 days for fibrinogen.
Positive acute-phase proteins serve (as part of the innate immune system) different physiological functions within the immune system.Some act to destroy or inhibit growth of microbes, e.g., C-reactive protein, mannose-binding protein, [3] complement factors, ferritin, ceruloplasmin, serum amyloid A and haptoglobin.
C1q can also be activated in other ways, for example by binding to pentraxins such as C-reactive protein [2] or directly to the surface of pathogens. [1] Such binding of C1q leads to conformational changes in the C1q molecule, which activates the associated C1r molecules. Active C1r cleaves the C1s molecules, activating them.
