Not detected in adult tissues.
Expressed in 4-cell embryo, morula and blastocyst. At 7.5 dpc, detected in the epiblast. At 10.0 dpc, expressed in the primordial germ cells. Expression decreases at 12.0 dpc in the embryonic gonads. At 14.5 dpc, expression is restricted to testis. 6 days after birth, still detected in primitive type A spermatogonia. Expressed in undifferentiated embryonic stem cells, but expression rapidly decreases upon differentiation.
DPPA2 (developmental pluripotency associated 2) is an embryo-cancer antigen that is coexpressed with cancer-testis antigens in non-small cell lung cancer. Dppa2 is closely linked SAP motif genes restricted to pluripotent cells and the germ line. It may play a role in maintaining cell pluripotentiality and in embryo preimplantation development.
