1 IKK beta plays an essential role in the phosphorylation of RelA/p65 on serine 536 induced by lipopolysaccharide. Serine v-rel reticuloendotheliosis viral oncogene homolog A (avian) Mus musculus
2 IKK beta plays an essential role in the phosphorylation of RelA/p65 on serine 536 induced by lipopolysaccharide. Serine v-rel reticuloendotheliosis viral oncogene homolog A (avian) Mus musculus
3 Here, we reported that LPS induced the phosphorylation of the p65 trans-activation domain on serine 536 in monocytes/macrophages. Serine v-rel reticuloendotheliosis viral oncogene homolog A (avian) Mus musculus
4 Using mouse embryonic fibroblasts lacking either IKK alpha or IKK beta, we found that IKK beta played an essential role in LPS-induced p65 phosphorylation on serine 536, while IKK alpha was partially required for the p65 phosphorylation. Serine v-rel reticuloendotheliosis viral oncogene homolog A (avian) Mus musculus
5 The LPS-induced p65 phosphorylation on serine 536 was independent of the phosphatidylinositol 3"-kinase/Akt signaling pathway. Serine v-rel reticuloendotheliosis viral oncogene homolog A (avian) Mus musculus
6 Furthermore, we found that the phosphorylation on serine 536 increased the p65 transcription activity. Serine v-rel reticuloendotheliosis viral oncogene homolog A (avian) Mus musculus
7 In summary, our results demonstrate that IKK beta plays an essential role in the LPS-induced p65 phosphorylation on serine 536, which may represent a mechanism to regulate the NF-kappa B transcription activity by LPS. Serine v-rel reticuloendotheliosis viral oncogene homolog A (avian) Mus musculus
