Recombinant Mouse CD55/DAF Protein, CF Summary

Details of Functionality
Measured by its binding ability in a functional ELISA. When rmCD55 is immobilized at 0.5 μg/mL, 100 μL/well, the concentration of rmCD97 that produces 50% of the optimal binding response is found to be approximately
0.15-0.5 μg/mL.

Background

CD55, also known as DAF or decay-accelerating factor, is a 70 - 75 kDa member of the RCA family of proteins. Human RCA (regulators of complement/C' activation) proteins are products of chromosome 1 genes that are ubiquitously expressed on cells exposed to plasma complement proteins (1 - 4). A hallmark of RCA proteins is the presence of 4 to 30 SCRs (short consensus repeats; also called CCPs for C' control protein modules) in their plasma-exposed regions. SCRs are characterized by a 60 - 65 amino acid (aa) module that contains a highly conserved Trp residue and two internal disulfide bonds that create a beta -barrel structure (1). Human CD55 is synthesized as a 381 aa precursor that contains a 34 aa signal sequence, a 319 aa mature region and a 28 aa C-terminal prosegment (5, 6). The mature region contains four SCR modules and a C-terminal O-glycosylated extension (7). Following cleavage of the prosegment, a serine is exposed that serves as an anchor for a GPI-linkage (8). Multiple polymorphisms are found in the molecule. Alternate splicing also exists. One form that may not be translated shows an intron insertion in the prosegment, resulting in a 79 aa substitution for the standard C-terminal 20 aas of the prosegment (6). Another form generates a truncated 199 aa precursor that cannot be membrane-bound and may not be secreted (9). Mature CD55 is 53% and 84% aa identical to mouse and monkey CD55, respectively. CD55 is known to bind CD97 via the first SCR (4). It also binds physiologically-generated C3 convertases with its second and third SCRs (7, 10). Binding results in an accelerated "decay", or dissociation of active C3 convertases, thus blocking the development of C' attack complexes on nonforeign cells (1, 2). Viruses and bacteria are also known to utilize multiple SCR sites for infection (4, 11). Finally, CD55 is broadly expressed in malignant tumors (12 - 13). Here, CD55 is involved in the promotion of tumorigenesis, decrease of complement mediated tumor cell lysis, autocrine loops for cell rescue and evasion of apoptosis, neoangiogenesis, invasiveness, cell motility, and metastasis via oncogenic tyrosine kinase pathway activation and CD97 binding (12 - 13).
