Description
This gene encodes a glycoprotein involved in the regulation of the complement cascade. Binding of the encoded protein to complement proteins accelerates their decay, thereby disrupting the cascade and preventing damage to host cells. Antigens present on this protein constitute the Cromer blood group system (CROM). Alternative splicing results in multiple transcript variants. The predominant transcript variant encodes a membrane-bound protein, but alternatively spliced transcripts may produce soluble proteins.
Bio-activity
Measured by its binding ability in a functional ELISA. When Recombinant Human (rh) CD55/DAF is coated at 1 μg/mL (100 μL/well), the concentration of rhCD97 that produces 50% of the optimal binding response is found to be approximately 0.5-2.5 μg/mL.
