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.
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.
| UniProt Protein Function: | CD55: 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. Belongs to the receptors of complement activation (RCA) family. 2 isoforms of the human protein are produced by alternative splicing. |

| NCBI Summary: | This gene encodes a protein involved in the regulation of the complement cascade. The encoded glycoprotein is also known as the decay-accelerating factor (DAF); binding of DAF to complement proteins accelerates their decay, disrupting the cascade and preventing damage to host cells. Antigens present on the DAF glycoprotein constitute the Cromer blood group system (CROM). Two alternatively spliced transcripts encoding different proteins have been identified. The predominant transcript encodes a membrane-bound protein expressed on cells exposed to plasma component proteins but an alternatively spliced transcript produces a soluble protein present at much lower levels. Additional, alternatively spliced transcript variants have been described, but their biological validity has not been determined. [provided by RefSeq, Jul 2008] |
