Anti-ADAM like decysin 1 antibodies are used in the immunodetection of the protein encoded by the ADAMDEC1 gene. In humans, the canonical protein has a reported length of 470 amino acid residues and a mass of 52.8 kDa. It is known to be a secreted protein. Alternative splicing is reported to yield 2 different isoforms for this protein. It is noted to be expressed highly in the small intestine and appendix, moderately in lymph node, mucosal lining of the colon, thymus, spleen and very weakly in the bone marrow. It is believed to play an important role in the control of the immune response and during pregnancy. Post-translational modifications have been described, including glycosylation. Other names for this target antigen include ADAM-like protein decysin-1, a disintegrin and metalloproteinase domain-like protein decysin-1, decysin, disintegrin protease, and M12.219.
