InnateDB Annotation
Summary
The major acute phase protein in humans that interacts with CFH of the alternative pathway of complement and C4BP of the classical complement pathway, limiting excessive complement activation
CRP induces FCAR surface expression, phagocytosis, and TNF secretion in neutrophils. In addition, CRP physically interacts with FCAR, and induces ERK phosphorylation, cytokine production, and degranulation in mast cells.
CRP promotes the differentiation of human monocytes toward a pro-inflammatory M1 macrophage phenotype. In addition, CRP treatment of M2 macrophages induced the expression of pro-inflammatory genes and a M1 phenotype.
InnateDB Annotation from Orthologs
Summary
[Mus musculus] Crp promotes the differentiation of human monocytes toward a pro-inflammatory M1 macrophage phenotype. In addition, Crp treatment of M2 macrophages induced the expression of pro-inflammatory genes and a M1 phenotype. (Demonstrated in human)
Entrez Gene
Summary The protein encoded by this gene belongs to the pentaxin family. It is involved in several host defense related functions based on its ability to recognize foreign pathogens and damaged cells of the host and to initiate their elimination by interacting with humoral and cellular effector systems in the blood. Consequently, the level of this protein in plasma increases greatly during acute phase response to tissue injury, infection, or other inflammatory stimuli. [provided by RefSeq, Sep 2009]
