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 .
Catabolite activator protein (CAP; also known as cAMP receptor protein, CRP) is a trans-acting transcriptional activator that exists as a homodimer in solution. Each subunit of CAP is composed of a ligand -binding domain at the N-terminus (CAP N , residues 1–138) and a DNA-binding domain at the C-terminus (DBD, residues 139–209).
[1] [2] CRP then activates transcription through direct protein–protein interactions with RNA polymerase. [1] [2] The genes regulated by CRP are mostly involved in energy metabolism, such as galactose, citrate, or the PEP group translocation system. [3] [4] In Escherichia coli, CRP can regulate the transcription of more than 100 genes. [5]
In contrast, C-reactive protein (with a half-life of 6–8 hours) rises rapidly and can quickly return to within the normal range if treatment is employed. For example, in active systemic lupus erythematosus, one may find a raised ESR but normal C-reactive protein. [citation needed] They may also indicate liver failure. [11]
The aPTT-based APC resistance test involves a modified aPTT test performed in the presence and absence of activated protein C (APC). [1] [5] The ratio of these aPTT values is calculated and is called the APC sensitivity ratio (APCsr) or simply APC ratio (APCr). [1] [5] This ratio is inversely related to the degree of APC resistance. [7]
C-reactive protein (CRP) is an acute phase protein. Therefore, it is a better marker for acute phase reaction than ESR. Therefore, it is a better marker for acute phase reaction than ESR. While ESR and CRP generally together correlate with the degree of inflammation, this is not always the case and results may be discordant [ 9 ] in 12.5% of ...
Reference ranges (reference intervals) for blood tests are sets of values used by a health professional to interpret a set of medical test results from blood samples. Reference ranges for blood tests are studied within the field of clinical chemistry (also known as "clinical biochemistry", "chemical pathology" or "pure blood chemistry"), the ...
Separating serum proteins by electrophoresis is a valuable diagnostic tool, as well as a way to monitor clinical progress.Current research regarding blood plasma proteins is centered on performing proteomics analyses of serum/plasma in the search for biomarkers.
