N.D., not determined.

a

Represents the log reciprocal of the agonist concentration required for half-maximal formation of the DRs*GX complex.

b

Represents the maximal amount of DRs*GX complex formed by the agonist, expressed relative to that of agonist A.

c

Expressed relative to that of agonist G.

d

Expressed relative to that of agonist A.
