The TNF family of cytokines essentially consists of two related regulatory factors: TNF-a (cachectin) and TNF-P (lymphotoxin). Although both molecules bind the same receptor and induce very similar biological activities, they display limited sequence homology. The human TNF-a and -P genes are located adjacent to each other on chromosome 6, being separated by only 1100 base pairs. Both contain three introns, and their expression appears to be coordinately regulated. TNF-a, sometimes referred to simply as TNF, has been studied in significantly greater detail than lymphotoxin.
