By differential screening of tumor necrosis factor ␣ (TNF-␣) and lipopolysaccharide (LPS)-activated endothelial cells (ECs), we have identified a cDNA clone that turned out to be a member of the inhibitor of apoptosis (iap) gene family. iap genes function to protect cells from undergoing apoptotic death in response to a variety of stimuli. These iap genes,(More)
The NF-κB family of transcription factors has an essential role in inflammation and innate immunity. Furthermore, NF-κB is increasingly recognized as a crucial player in many steps of cancer initiation and progression. During these latter processes NF-κB cooperates with multiple other signaling molecules and pathways. Prominent nodes of crosstalk are(More)
Re-uptake of gamma-aminobutyric acid (GABA) into presynaptic specializations is mediated by the GABA transporter 1 (GAT1), a member of the SLC6 gene family. Here, we show that a motif in the COOH terminus of GAT1 ((566)RL(567)), which is conserved in SLC6 family members, is a binding site for the COPII coat component Sec24D. We also identified residues in(More)

IKKb/IKBKB (IkB kinase beta), also designated as IKK2, was named after its function of phosphorylating IkB molecules, the inhibitors of NF-kB transcription factors. The kinase activity of IKKb targets two adjacent serine residues of IkB leading to ubiquitination and proteasomal degradation of the inhibitor, followed by release and activation of NF-kB. Many(More)
Tissue remodeling or regeneration is believed to initiate from multipotent stem and progenitor cells. We report here the establishment of two spontaneously immortalized adult non-tumorigenic human prostate epithelial cell lines, NHPrE1 and BHPrE1. NHPrE1 (CD133(high)/CD44(high)/OCT4(high)/PTEN(high)) was characterized as a putative progenitor cell, and(More)
BACKGROUND The use of spectrally distinct variants of green fluorescent protein (GFP) such as cyan or yellow mutants (CFP and YFP, respectively) is very common in all different fields of life sciences, e.g. for marking specific proteins or cells or to determine protein interactions. In the latter case, the quantum physical phenomenon of fluorescence(More)
Fluorescence- or Förster resonance energy transfer (FRET) is a measurable physical energy transfer phenomenon between appropriate chromophores, when they are in sufficient proximity, usually within 10 nm. This feature has made them incredibly useful tools for many biomedical studies on molecular interactions. Furthermore, this principle is increasingly(More)
BACKGROUND I-kappa B kinase 2 (IKK2 or IKK-beta) is one of the most crucial signaling kinases for activation of NF-kappa B, a transcription factor that is important for inflammation, cell survival and differentiation. Since many NF-kappa B activating pathways converge at the level of IKK2, molecular interactions of this kinase are pivotal for regulation of(More)
