protein protein CD59-like glycoprotein protein A protein that is a translation product of the human CD59 gene, a 1:1 ortholog thereof, or pro-orthologs thereof. CD59-like Category=gene. Requested by=CL. Pro-orthology refers to, in this case, after-speciation gene duplication in the non-human species (aka 1:many orthology). This gene is present as a single copy in human and has undergone a lineage-specific duplication in mouse. CD59 antigen has a core architecture consisting of one UPAR/Ly-6 domain (Pfam:PF00021), a small domain of about 70 amino acids and containing 5 conserved disulfide bonds. It is both N- and O-glycosylated and is a GPI-anchored protein that releases soluble forms in some tissues. PIRSF:PIRSF038782 PR:000001809
