Ecto-ADP-ribosyltransferase 4 is an enzyme that in humans is encoded by the ART4 gene.^[5][6] ART4 has also been designated as CD297 (cluster of differentiation 297).

Function[edit]

This gene encodes a protein that contains a mono-ADP-ribosylation (ART) motif. It is a member of the ADP-ribosyltransferase gene family but enzymatic activity has not been demonstrated experimentally. Antigens of the Dombrock blood group system are located on the gene product, which is glycosylphosphatidylinositol-anchored to the erythrocyte membrane. Allelic variants, some of which lead to adverse transfusion reactions, are known.^[6]

Blood group antigens[edit]

Several antigens have been recognised in this family. These are DO*A, DO*JO1, DO*A-WL, DO*DOYA, DO*B, DO*B-WL, DO*B-SH-Q149K, DO*B-(WL)-I175N, DO*HY1, DO*HY2 and DO*DOMR.
