CAMPATH-1 antigen, also known as cluster of differentiation 52 (CD52), is a glycoprotein that in humans is encoded by the CD52 gene.
CD52 is present on the surface of mature
sperm cells
.
CD52 is a peptide of 12 amino acids, anchored to glycosylphosphatidylinositol (GPI). Since it is highly negatively charged and present on sperm cells and lymphocytes, it has been conjectured that its function is anti-adhesion, allowing cells to freely move around.[5]
CD52 binds the ITIM (immunoreceptor tyrosine-based inhibitory motif)-bearing sialic acid-binding lectin SIGLEC10.
Clinical significance
It is associated with certain types of lymphoma.[6]
It is the protein targeted by
glatiramer demonstrated reduction in both relapse rate and accumulated disability. 20% patients randomised to interferon beta 1a had "sustained accumulation of disability" compared with 13% in the alemtuzumab group.[8]
