  Materials and methods Results Discussion PYR-41 inhibits UBE1 activity that catalyses an initial step in the ubiquitination reaction. In the present study, we examined the role of this enzyme in sperm-egg fusion by inhibiting UBE1 enzymatic activity in eggs. Our results suggest that PYR-41

  The human serotonin (5-hydroxytryptamine; 5-HT) receptor family consists of 14 receptor subtypes to date, which are primarily G protein-coupled receptors (GPCRs) with 5-HT3 being the sole ligand-gated ion channel (Alexander et al., 2017). These receptors are widely distributed in the central and per

  On the other hand, the properties of collagen materials could be efficiently improved by proper chemical modification. The crosslinking agents for collagen generally involve aldehydes (e.g., glutaraldehyde (GA), isocyanates (e.g., hexamethylene diisocyanate (HMDI), photoreactive agents, polyepoxy co

  Accumulated evidence indicates that apelin plays a protective role in ischemic stroke, contributing to post-stroke recovery (Yang et al., 2014; Chen et al., 2015; Xin et al., 2015; Yan et al., 2015). Apelin gene (APLN) encodes prepro-apelin with 77 amino acids, while the C-terminal 23 ampa receptors

  2021-08-13

  

  Ligand-independent activation of neuronal nuclear estrogen receptors may also continue to occur in absence of ovarian estrogens. AF-1 requires intracellular kinase cascade-dependent phosphorylation of specific residues in the A/B domain of nuclear estrogen receptors (Le Goff et al., 1994; Kato et a

  The action of 17-pt-PGE2 as an EP1 receptor agonist [34] was demonstrated in several experimental settings, including cancer, neurons, vascular system, kidney and was confirmed by application of EP1 receptor selective antagonists [35], [36], [37], [38], [39], [40], [41]. Receptor binding studies in

  The glycolytic pathway is a catabolic route that ends with the synthesis of pyruvate (Pyr). In Arabidopsis embryos, the conversion of phosphoenolpyruvate (PEP) to Pyr, catalyzed by pyruvate kinase (PK), is mainly located in the plastids [10], [11]. The preceding reaction is catalyzed by enolase (ENO

  Intriguingly, one E2 residue may serve as a molecular ‘gate’ to allow the C-terminus of ubiquitin to access the closed E2~Ub conformations favorable for ubiquitin transfer. This residue, Asp87 in UbcH5 family members, resides on one side of the opening that leads to the active site Cys (Fig. 4D). In

  RING dimerization RING-type domains are found in many different structural contexts. While many exist as single-chain cdc42 inhibitor (Fig. 3A), a notable feature of RING-type E3s is their tendency to form homodimers and heterodimers (Fig. 3C–F). Homodimeric RING-type E3s include cIAP, RNF4, BIRC

  Thymine glycol severely inhibits DNA synthesis by replicative DNA polymerases and requires the action of specialized DNA polymerases for translesion synthesis (e.g. Ref. [26]). Eukaryotic and archaeal RNAPs were shown to pause after nucleotide insertion opposite TG [27,28]. Surprisingly, we found th
