The T cell receptor TCR pathway
2020-08-18
The T cell receptor (TCR) pathway is associated with T cell activation and differentiation. When specific antigen peptides are recognized by the TCR, lymphocyte-specific protein tyrosine kinase (lck) phosphorylates the immune-receptor tyrosine-based activation motifs (ITAMs) of the TCR-CD3 complex a

Author Contributions Acknowledgments Introduction Many anticancer agents bind covalently to DNA, introduce bulky adducts, and inhibit DNA metabolic processes including repair, replication and transcription.1., 2., 3. Frequently, the first enzymes to encounter DNA adducts are DNA helicases.

Acknowledgements Membrane-bound proton-translocating inorganic pyrophosphatases (H-PPase; EC 3.6.1.1) belong to a recently identified category of proton pumps, distinct from F-, P-, and V-ATPases, which utilize pyrophosphate hydrolysis as the driving force for H movement across biological membr

2020-08-17
Within the BLA, both CRF and the CRF1 receptor have been shown to functionally regulate synaptic activity. In vivo, CRF release into the BLA originates from projections from the CeA (Roozendaal, Brunson, Holloway, McGaugh, & Baram, 2002). Central administration of both CRF and CRF1 agonists has been

Based on both the observational and theoretical data generated in this study, it appears that the mechanism(s) underlying lower IFM CPT1 activity is complex. Modeling enzyme activity versus alterations in catalytic efficiency (Fig. 3A) suggests that the observed age-associated changes in Km and Vmax

2020-08-17
EphB4 appears to be a low-affinity receptor for rhEpo based on the biochemical data. The concentration of rhEpo used for the biological experiments (50 IU/ml) corresponds to 10–15 nM, which is 1% to 2% of the KD value (KD = 881 nM) for the binding of rhEpo to EphB4, as measured in the MST assay. The

Here, we show that cpg2 is expressed only in the ochratoxin and encodes a protein that localizes specifically to the postsynaptic endocytic zone of excitatory synapses. We present evidence that CPG2 is a critical component of the postsynaptic endocytic pathway that mediates both constitutive and ac

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

Inappropriate heme metabolism has been linked to several neuropsychiatric disorders. In the hippocampi of Alzheimer\'s disease (AD) patients, for example, heme was found to binds intracellular amyloid β (Aβ), resulting in reduced heme bioavailability and its functional deficiency (Atamna and Frey, 2

Here, we describe preparation of three stable conjugates that are linked by either oxyester, disulfide, or isopeptide bonds (Fig. 10.1). Each of these conjugates depends upon the prior purification of E2 and ubiquitin proteins that have been engineered to favor specific linkages. For the oxyester- a

The component E1 of PDHc (PDHc-E1) catalyzes the first step of multistep processes, using thiamine diphosphate (ThDP) and Mg2+ as cofactors.15, 16 Especially, this PDHc-E1 catalyzed process is a rate limiting step among multistep processes. Accordingly, the PDHc should be inactive by inhibiting the

All components of the UPP were predicted to be susceptible to oxidative stress due to the cysteine residues in their active sites [36]. Curcusone D inhibits DUBs but has no significant effect on the action of E1, E2s, E3s, or the proteasome, which indicates that the targets of the ROS induced by cur

The first ones class A receptors found as heterodimers were reported by Gomes et al. (2000), who identified a heteromer constituted by two subtypes of opioid receptors (μ and δ) in heterologous cells. The same year, Ginés et al. (2000) showed the first heteromer composed of two different receptors,

HvPap-1, a member of the cathepsin F-like family, was identified in germinating barley seeds (Sreenivasulu et al., 2008). This enzyme participates in the mobilization of stored proteins (mainly hordeins) during the last phase of grain germination, and its activity is modulated by a propeptide or/and
