VGB3 Induces Apoptosis by Inhibiting Phosphorylation of NF-κB p65 at Serine 536 in the Human Umbilical Vein Endothelial Cells
Background and objectives: Nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) inhibition results in an increase in apoptosis. It has been demonstrated that NF-κB subunit p65 phosphorylation at the IκB kinase phosphorylation site serine 536 (Ser536) is essential for the NF-κB nuclear translocation and activation. Therefore, NF-κB can be downregulated by suppressing its phosph...
متن کاملCharacterization of the in vivo sites of serine phosphorylation on Lck identifying serine 59 as a site of mitotic phosphorylation.
The lymphocyte-specific protein-tyrosine kinase Lck plays a critical role in T cell activation. In response to T cell antigen receptor binding Lck undergoes phosphorylation on serine residues that include serines 59 and 194. Serine 59 is phosphorylated by ERK mitogen-activated protein kinase. Recently, we showed that in mitotic T cells Lck becomes hyper-phosphorylated on serine residues. In thi...
متن کاملAkt attenuation of the serine protease activity of HtrA2/Omi through phosphorylation of serine 212.
The serine protease HtrA2/Omi is released from the mitochondria into the cytosol following apoptosis stimuli, leading to the programmed cell death in caspase-dependent and -independent manners. The function of HtrA2/Omi closely relates to its protease activity, which is required for cleavage of its substrate such as the members of the X-linked inhibitor of apoptotic protein family. However, the...
متن کاملPhosphorylation of the menin tumor suppressor protein on serine 543 and serine 583.
Multiple endocrine neoplasia type 1 (MEN-1) is a heritable syndrome typified by tumors in multiple endocrine organs, including the pituitary, parathyroids, and pancreatic islets. MEN-1 is attributable to mutations in the MEN1 tumor-suppressor gene that encodes the menin protein. Recent studies have implicated menin in transcriptional regulation and in covalent histone modification; however, lit...
متن کاملNegative regulation of Raf-1 by phosphorylation of serine 621.
The elevation of cyclic AMP (cAMP) levels in the cell downregulates the activity of the Raf-1 kinase. It has been suggested that this effect is due to the activation of cAMP-dependent protein kinase (PKA), which can directly phosphorylate Raf-1 in vitro. In this study, we confirmed this hypothesis by coexpressing Raf-1 with the constitutively active catalytic subunit of PKA, which could fully r...
