Gene Gene information from NCBI Gene database.
Entrez ID 1604
Gene name CD55 molecule (Cromer blood group)
Gene symbol CD55
Synonyms (NCBI Gene)
CHAPLECRCROMDAFTC
Chromosome 1
Chromosome location 1q32.2
Summary 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 t
