Gene: Cd55 (CD55 molecule (Cromer blood group)) Rattus norvegicus
Symbol: Cd55
Name: CD55 molecule (Cromer blood group)
RGD ID: 620651
Description: Exhibits enzyme inhibitor activity. Involved in several processes, including maternal process involved in parturition; negative regulation of complement activation; and spermatogenesis. Localizes to apical plasma membrane. Used to study neuroblastoma and proteinuria. Human ortholog(s) of this gene implicated in prostate cancer and protein-losing enteropathy. Orthologous to human CD55 (CD55 molecule (Cromer blood group)); PARTICIPATES IN complement system pathway; coagulation cascade pathway; myocarditis pathway; INTERACTS WITH 1,3-dinitrobenzene; 17alpha-ethynylestradiol; 17beta-estradiol.
Type: protein-coding
RefSeq Status: VALIDATED
Also known as: CD55 antigen; CD55 molecule, decay accelerating factor for complement; complement decay-accelerating factor; Daf; Daf1; decay accelarating factor 1; decay accelerating factor 1; decay accelerating factor GPI-form; decay-accelarating factor; glycosylphophatidylinositol-anchored form
