The invention provides soluble forms of the Fas (Apo-1 ) protein comprising both the intracellular and extracellular domains of the full-length polypeptide. Exemplified is a naturally-occurring splice variant of the Fas gene, Fas.DELTA.TM, which lacks the transmembrane domain of the native antigen. DNA encoding the protein, cells expressing the recombinant DNA, and methods of using the protein and DNA are also provided.
