In Vitro Processing of Human Tumor Necrosis Factor-α
1 Oct 1995
Abstract excerpt
Tumor necrosis factor (TNF)-alpha is initially synthesized as a membrane-bound, cell-associated 26-kDa protein that is further cleaved to yield the soluble 17-kDa form. By using a radiolabeled in vitro translated TNF-alpha precursor we detected a serine proteinase processing activity present in crude membrane preparations of monocytic cells able to generate a 17-kDa active protein. A similar processing pattern...
