  2019-10-28

  

  The Eph–ephrin signaling system has the ability to elicit bidirectional signaling, classical forward signaling by both Eph receptor via its intrinsic tyrosine kinase activity and reverse signaling by the transmembrane ephrin ligand via its cytoplasmic domain [38], [39]. Thus when EphB4 binds with ep

  2019-10-28

  

  Enzyme activations Activated proteinases can unleash a deluge of tissue damage (Zucker et al., 2009). Once activated, the essential enzymes such as serine proteases and cysteine proteases cannot discriminate between self and non-self, burning away self-tissues (Chien et al., 2009, Laskar et al.,

  2019-10-28

  

  Within the X1CX3PX5RX7 motif of several prokaryotic FGE substrates, the residues of X3, X5, and X7 are variably found as mixtures of alanine, glycine, threonine, or serine residues [26], [27]. The docked model of our identified HCTPRRP motif revealed that position X1 (H1) and position X7 (P7) were n

  2019-10-28

  

  In addition to providing substantial insight into substrate recognition, structural studies have revealed important details about mechanisms of glycosylation and HCF-1 cleavage [28,30,33]. Activation of the nucleotide-sugar is accomplished through interactions of the β-phosphate with the N-terminus

  In this study we have explored a functional role of the oxysterol/EBI2 system in this process. In 2011 we and others reported the discovery of oxysterols as ligands for EBI2 [6], [7]. Oxysterols are metabolites generated by hydroxylation of cholesterol and have been linked to a variety of fundamenta

  2019-10-28

  

  EBI2 and its ligand(s) EBI2 was found in a screen of upregulated genes in human B cells upon infection with EBV [1]. EBI2 is a G-protein (Gαi type) coupled receptor [2] but as long as 18 years after its discovery the nature of its ligand remained undisclosed. With the help of transfected cell lines

  2019-10-28

  

  Itch, also known as astrophin-1 interacting protein-4 (AIP4), is a HECT domain-E3 ligase. It was discovered in 1998 in mouse coat color genetic studies which displayed the disruption caused by the Itch gene inducing a lethal autoimmune inflammatory condition. The substrates of Itch are transmembrane

  Compound A and Compound B (Fig. 4) were found in our in vitro screening assays and have similar CRF1 receptor in vitro profiles (Table 1). When binding was investigated using [125I]-CRF in ex vivo assay, Compound A inhibited binding of [125I]-CRF both in the frontal cortex and the pituitary; however

  2019-10-25

  

  The serotonin transporter gene () encodes an integral membrane protein that transports serotonin from the synaptic spaces into the presynaptic neurons. The encoded protein terminates the action of serotonin and recycles it in a sodium-dependent way. This protein is a target of psychomotor stimulants

  Although further experiments are needed to determine definitively whether D–ETB receptor heterodimers exist, for example, by using fluorescence resonance Pemetrexed transfer analysis or co-immunoprecipitation of receptors, the results of the study by Zeng and colleagues appear to indicate that D–ET

  2019-10-25

  

  Introduction Fibroblast growth factors (FGF) are a family of 18 secreted ligands that bind to four receptor tyrosine kinase (RTK) FGF receptors (FGFR1–4). The interaction of FGFs with their cognate receptors results in the activation of a number of downstream signaling pathways, including the MAP

  Ultrasound is an acoustic wave with a frequency >20 kHz that needs a medium to propagate [20]. Accompanied by the spread of an ultrasonic wave, a series of alternating cycles of compression and rarefaction emerge in the liquid medium. During the rarefaction cycle, microbubbles are formed because of

  A wealth of studies support the key role of high NO in promoting higher blood flow and thus greater O2 delivery to working tissues in healthy Tibetans and thus partly compensate hypoxia induced low arterial O2 content [7,9,27]. We observed high eNOS mRNA, protein and enzyme activity in Ladakhi women

  Upon Edn ligand binding, endothelin receptors can induce a variety of intracellular signaling cascades leading to diverse cellular responses such as contraction in the case of smooth muscle cells, or cell growth and mitogenesis. Ednrs are expressed in a variety of cell types and tissues, for example
