1 Involvement of a putative protein-tyrosine phosphatase and I kappa B-alpha serine phosphorylation in nuclear factor kappa B activation by tumor necrosis factor. Serine NFKB inhibitor alpha Homo sapiens
2 The presence of a tyrosine phosphorylation site on the inhibitor of NF-kappa B (I kappa B-alpha) suggested that it could be a target for TNF/okadaic acid-induced tyrosine dephosphorylation. Tyrosine NFKB inhibitor alpha Homo sapiens
3 The presence of a tyrosine phosphorylation site on the inhibitor of NF-kappa B (I kappa B-alpha) suggested that it could be a target for TNF/okadaic acid-induced tyrosine dephosphorylation. Okadaic Acid NFKB inhibitor alpha Homo sapiens
4 The presence of a tyrosine phosphorylation site on the inhibitor of NF-kappa B (I kappa B-alpha) suggested that it could be a target for TNF/okadaic acid-induced tyrosine dephosphorylation. Tyrosine NFKB inhibitor alpha Homo sapiens
5 However, no tyrosine phosphorylation was detected on I kappa B-alpha fron unstimulated cells, while TNF/okadaic acid-treated cells showed increased phosphorylation of I kappa B-alpha exclusively at serine residue(s). Okadaic Acid NFKB inhibitor alpha Homo sapiens
6 However, no tyrosine phosphorylation was detected on I kappa B-alpha fron unstimulated cells, while TNF/okadaic acid-treated cells showed increased phosphorylation of I kappa B-alpha exclusively at serine residue(s). Serine NFKB inhibitor alpha Homo sapiens
7 Treatment of cells with pervanadate inhibited TNF-induced I kappa B-alpha phosphorylation and degradation, whereas the serine protease inhibitors tosylphenylalanyl chloromethyl ketone and N alpha-p-tosyl-L-lysine chloromethyl ketone prevented TNF-induced I kappa B-alpha degradation and NF-kappa B nuclear translocation, but not the TNF-induced phosphorylation of I kappa B-alpha. pervanadate NFKB inhibitor alpha Homo sapiens
