Protein

C-reactive protein

Gene

CRP

Organism
Mesocricetus auratus (Golden hamster)
Status
Reviewed - Annotation score: 3 out of 5- Experimental evidence at transcript leveli

Functioni

Displays several functions associated with host defense: it promotes agglutination, bacterial capsular swelling, phagocytosis and complement fixation through its calcium-dependent binding to phosphorylcholine. Can interact with DNA and histones and may scavenge nuclear material released from damaged circulating cells (By similarity).By similarity

Cofactori

Ca2+By similarityNote: Binds 2 calcium ions per subunit.By similarity
