Human DAF/CD55 protein (Recombinant) (C-His) (STJP002674)
SPECIFICATIONS
HostHEK293 cells
ConjugationUnconjugated
ImmunogenRecombinant Human CD55/DAF Protein is produced by HEK293 expression system. The target protein is expressed with sequence (Asp35-Ser353) of human CD55/DAF (Accession #NP_000565.1) fused with a 6×His tag at the C-terminus.

Additional Info
| Post Translational Modifications | The Ser/Thr-rich domain is heavily O-glycosylated. |
| Function | This protein recognizes C4b and C3b fragments that condense with cell-surface hydroxyl or amino groups when nascent C4b and C3b are locally generated during C4 and c3 activation. Interaction of daf with cell-associated C4b and C3b polypeptides interferes with their ability to catalyze the conversion of C2 and factor B to enzymatically active C2a and Bb and thereby prevents the formation of C4b2a and C3bBb, the amplification convertases of the complement cascade. Inhibits complement activation by destabilizing and preventing the formation of C3 and C5 convertases, which prevents complement damage. (Microbial infection) Acts as a receptor for Coxsackievirus A21, coxsackieviruses B1, B3 and B5. (Microbial infection) Acts as a receptor for Human enterovirus 70 and D68 (Probable). (Microbial infection) Acts as a receptor for Human echoviruses 6, 7, 11, 12, 20 and 21. |
