  Conflict of interests Introduction Ubiquitylation is a post-translational modification which impacts almost every biological process in the cell. Dysregulation of the ubiquitylation pathway is associated with several diseases, including cancer, neurodegenerative disorders, and immunological dy

  Activity-based probes Characterization of coronavirus-encoded DUBs with activity-based probes To study the activity of specific DUBs, investigators frequently take advantage of the ~10kDa (monoUb or Ubl ABP) or ~20kDa (DiUb ABP) increase in MW on probe labeling. SDS-PAGE analysis or blotting f

  In this study, using REMD with the crystal environment, we investigate the effect of cryo-cooling on the crystal structure of Escherichia coli DHFR. DHFR is an important model enzyme (for review, see, e.g., (30)), and has been studied for decades (31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43).

  Acetylcholinesterase and cholinergic signaling The concept of a synapse between a neuron and an innervated cell, and the receptors that mediated their interaction, was developed by Bernard, Ehrlich, Sherrington, Langley and others (see [7], [8], [9]. It was long debated whether transmission of ne

  Our previous work has demonstrated that two glutamate residues (Glu-305 and Glu-331 in murine and human TPP II) in the active site are important for exopeptidase activity in mTPP II [17]. At least one of these, Glu-331, seems to form a salt bridge to the N-terminal amino group of the substrate, posi

  Collagen type 1 is the most abundant extracellular matrix (ECM) protein found in vertebrates. Collagen exerts its role as a load bearing structure and regulator of cell function, only after it has assembled into fibrils., The equilibrium between the synthesis and degradation of collagen fibrils and

  As an endogenous negative modulator, CRBN inhibits AMPK’s activation (phosphorylation of Thr172) by directly binding to the α-subunit of AMPK, disrupting γ-subunit recruitment to the AMPK complex (Lee et al., 2011, Lee et al., 2013). In our study, we did not focus on AMPK activation, since only a si

  The modification of proteins with the small 76-amino Tankyrase Inhibitors 49 protein ubiquitin (Ub) plays a central role in many key cellular processes. Ubiquitylation of a target protein requires the concerted action of a cascade of three enzymes (Figure 1). The ubiquitin-activating enzyme (E1) ca

  Discussion The biochemical separation of exonuclease activity from DNA-PK dependent endonuclease activity reported in this manuscript is consistent with genetic separation of Artemis enzymatic activity. Mutations in the protein which result in disruption of endonuclease activity have no effect on

  In this work, we directly compared the effects on transcription by E. coli RNAP of several types of lesions commonly found in the genomic DNA: thymine dimer (CPD, cyclobutane pyrimidine dimer); 1,N6-ethenoadenine (εA); abasic site (AP); 8-oxoguanine (8oxoG), and thymine glycol (TG).

  The overall shape of p110α/iSH2 is dramatically different from DGKB or SK1, instead of forming a homodimer, p110α/iSH2 heterodimer has a triangular shape with iSH2 laying on the top and ABD, RBD, helical and kinase domain of p110α sitting in the bottom (Fig. 2B) (Gabelli et al., 2010; Huang et al.,

  In conclusion, our data demonstrated that montelukast and pranlukast non-competitively blocked P2Y signaling in several cell systems, but in a relatively nonsubtype-specific manner. The functional antagonism was especially evident at heterologously expressed P2Y1 and P2Y6 receptors, at which IC50 va
