SYNONYMS
CD55 Antigen, DAF, CD55 Molecule, CHAPLE, Cromer Blood Group Antigen, Complement Decay-Accelerating Factor, CROM.
INTRODUCTION
Decay-Accelerating Factor Isoform 1 or CD55, is a protein that attached to the cell membrane through glycophosphatidylinositol (GPI) anchor. CD55 regulates the complement system in the outer membrane. The protein is a receptor to many types of enteroviruses such as coxsackieviruses. CD55 is widely scattered amidst hematopoietic & non-hematopoietic cells. The CD55 has a crucial part in tumorigenesis, autocrine loops for cell rescue and evasion of apoptosis, cell motility, invasiveness etc.
DESCRIPTION
CD55 produced in Sf9 Baculovirus cells is a single, glycosylated polypeptide chain (35-353 a.a.) and fused to a 9 aa His Tag at C-terminus containing a total of 328 amino acids and having a molecular mass of 36kDa. CD55 shows multiple bands between 40-57kDa on SDS-PAGE, reducing conditions and purified by proprietary chromatographic techniques.
