Disease
TNFB_HUMAN Genetic variations in LTA are a cause of susceptibility psoriatic arthritis (PSORAS) [MIM:607507. PSORAS is an inflammatory, seronegative arthritis associated with psoriasis. It is a heterogeneous disorder ranging from a mild, non-destructive disease to a severe, progressive, erosive arthropathy. Five types of psoriatic arthritis have been defined: asymmetrical oligoarthritis characterized by primary involvement of the small joints of the fingers or toes; asymmetrical arthritis which involves the joints of the extremities; symmetrical polyarthritis characterized by a rheumatoidlike pattern that can involve hands, wrists, ankles, and feet; arthritis mutilans, which is a rare but deforming and destructive condition; arthritis of the sacroiliac joints and spine (psoriatic spondylitis).
Function
TNFB_HUMAN Cytokine that in its homotrimeric form binds to TNFRSF1A/TNFR1, TNFRSF1B/TNFBR and TNFRSF14/HVEM. In its heterotrimeric form with LTB binds to TNFRSF3/LTBR. Lymphotoxin is produced by lymphocytes and cytotoxic for a wide range of tumor cells in vitro and in vivo.

Publication Abstract from PubMed
The X-ray crystal structure of the complex of the extracellular domain of the human 55 kd tumor necrosis factor (TNF) receptor with human TNF beta has been determined at 2.85 A resolution. The complex has three receptor molecules bound symmetrically to one TNF beta trimer. The receptor fragment, a very elongated end to end assembly of four similar folding domains, binds in the groove between two adjacent TNF beta subunits. The structure of the complex defines the orientation of the ligand with respect to the cell membrane and provides a model for TNF receptor activation. The novel fold of the TNF receptor structure is likely to be representative of the nerve growth factor (NGF)/TNF receptor family as a whole.
