Protein
C-reactive protein
Gene
Crp, Ptx1
Organism
Rattus norvegicus (Rat)
Status
Reviewed - Annotation score: 5 out of 5 - Experimental evidence at protein 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.

Cofactori

Binds 2 calcium ions per subunit By similarity.

Interactioni

Subunit structurei

Homopentamer. Pentaxin (or pentraxin) have a discoid arrangement of 5 non-covalently bound subunits. Two of the five chains form a dimer linked by two interchain disulfide bonds located in the C-terminal heptapeptide and specific to rat CRP.
