Protein Function | mediate phagocytosis of Saccharomyces,E. coli and S. aureus; Cl-P1 in the vascular spaces acts as a scavenger receptor to scavenge released neutrophil glycoproteins, both locally at sites of inflammation or systemically,when they are released in the circulation; CL-P1 bound CRP in a charge-dependent manner interaction mediated activation of the classical complement activation pathway. Collectin-12 (collectin placenta 1, CL-P1, or CL-12) is a newly identified pattern recognition molecule of the innate immune system. Recent evidences show that CL-12 plays important roles not only in innate immune protection against certain clinically important pathogens but also in scavenging of host molecules, leukocyte recruitment, and cancer metastasis. |
