The present invention generally concerns novel proteins which bind to the intracellular domains of the p55 and p75 TNF-Rs and the Fas-R, which are capable of modulating the function of the p55 and p75 TNF-Rs and the Fas-R, and the DNA sequences which encode them. The present invention also concerns new soluble oligomeric TNF-Rs, oligomeric Fas-Rs and oligomeric receptors having a mixture of TNF-Rs and Fas-Rs. In addition, the present invention concerns methods of preparation and uses of all of the aforementioned.
