SUSD4, Human (HEK293, Fc)

SUSD4 protein acts as a complement inhibitor by disrupting classical C3 convertase formation. Isoform 3 specifically inhibits the classical complement pathway, and membrane-bound isoform 1 inhibits C3b deposition through classical and alternative pathways, showcasing SUSD4's regulatory role in complement activation and potential significance in immune response modulation. SUSD4 Protein, Human (HEK293, Fc) is the recombinant human-derived SUSD4 protein, expressed by HEK293 , with C-mFc labeled tag.
