Target Information

CD55 (decay-accelerating factor, DAF) is a GPI-anchored membrane glycoprotein that protects autologous cells from classical and alternative pathways of the complement cascade.
Bidirectional interactions between CD55 and CD97 are involved in T cell regulation, and CD55 can regulate complement when bound to CD97.
In tumors, CD55 promotes neoangiogenesis, tumorigenesis, invasiveness, and evasion of apoptosis.
CD55 is a 70 kDa glycoprotein (in erythrocytes) anchored in the membrane by a glycosylphosphatidylinositol tail. In other cells, the apparent molecular weight is somewhat larger and has a substantial content of O-glycans.
CD55 binds to activated C4b or C3b complement fragments on the cell surface, preventing assembly and accelerating decay of both classical and alternative pathways.
CD55 carries the Cromer-related blood group antigens. Two alternatively spliced transcripts encoding CD55 have been identified: one encoding a membrane-bound protein expressed on cells exposed to plasma component proteins, and another encoding a soluble protein present at much lower levels.
CD55 has been studied for its role in prostate cancer growth and survival.
