Summaries for CD55 Gene

Entrez Gene Summary for CD55 Gene

  • 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. [provided by RefSeq, Jul 2014]

GeneCards Summary for CD55 Gene

CD55 (CD55 Molecule (Cromer Blood Group)) is a Protein Coding gene. Diseases associated with CD55 include Complement Hyperactivation, Angiopathic Thrombosis, And Protein-Losing Enteropathy and Protein-Losing Enteropathy. Among its related pathways are Hematopoietic cell lineage and Immune response Lectin induced complement pathway. GO annotations related to this gene include lipid binding and virus receptor activity. An important paralog of this gene is CFH.

UniProtKB/Swiss-Prot for CD55 Gene

  • 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.

  • (Microbial infection) Acts as a receptor for coxsackievirus A21, coxsackieviruses B1, B3 and B5 (PubMed:9151867). Acts as a receptor for human enterovirus 70 and D68 (Probable) (PubMed:8764022). Acts as a receptor for human echoviruses 6, 7, 11, 12, 20 and 21 (PubMed:7525274).

Variants for CD55 Gene

Polymorphic Variants from UniProtKB/Swiss-Prot for CD55 Gene

DAF_HUMAN-P08174
Responsible for the Cromer blood group system (CROM) [MIM:613793]. It consists of at least 8 high-incidence (Cr(a), Tc(a), Dr(a), Es(a), WES(b), UMC, IFC and GUTI) and three low-incidence (Tc(b), Tc(c) and WES(a)) antigens that reside on DAF. In the Cromer phenotypes Dr(a-) and Inab there is reduced or absent expression of DAF, respectively. In the case of the Dr(a-) phenotype, a single nucleotide substitution within exon 5 accounts for two changes: a simple amino acid substitution, Leu-199 that is the basis of the antigenic variation, and an alternative splicing event that underlies the decreased expression of DAF in this phenotype. The Inab phenotype is a very rare one in which the red blood cells lack all Cromer system antigens. The red blood cells of individuals with Inab phenotype have a deficiency of DAF, but these individuals are not known to have any associated hematologic or other abnormalities (PubMed:12675719).
