Human DR3 (TRAMP, LARD) was redesignated TNF receptor superfamily member 25. TL1A is a ligand which can induce apoptosis through a cytoplasmic death domain similar to the CD178-CD95 (FasL-Fas) interaction. Alternatively, engagement of DR3 on T cells can synergize with other activating signals to enhance IFN g production.
Recombinant DR3-muIg binds to recombinant TL1A in EIA.
Molecular Structure: A soluble fusion protein combining the extracellular (150aa) domain of human DR3 and murine IgG2a Fc and hinge region (233aa), with a predicted monomeric molecular weight of 42.9 kd.
N-teminal sequence: (27) GTRSP
