  A growing number of other post-translational modifications are implicated in regulation of the ubiquitin system, including substrate modification by hydroxylation, glycosylation, acetylation, methylation, modification by poly(ADP-ribose) (PAR), and attachment of ubiquitin-like modifiers. The HIF1-α

  Dysfunction of the ubiquitin-proteasome system causes abnormal organelle morphology and impairs sperm formation and maturation steps resulting in male infertility [[7], [8], [9]]; this indicates that ubiquitination is essential for spermatogenesis and sperm function during fertilization. β-catenin i

  Conclusions In this paper we describe the recombinant expression and characterization of ParI, a C5-DNA-MTase from P. arcticus 273–4. To our knowledge, this is the first characterization of an orphan C5-DNA-MTase from a psychrophilic bacterium. The C5-DNA-MTase could not be expressed in regular E

  Cell migration and invasion are central processes in the development and metastasis of cancer. The regulation of cell migration by DDR1 has been reported in many types of cancer cell lines; however, conflicting results have been reported regarding the inhibitory as well as promotive effects of DDR1

  p27Kip1 is a critical component of the cell cycle machinery [15]. As an inhibitor of cyclin E-Cdk2, p27Kip1 plays a pivotal role in controlling cell proliferation, S-phase entry, and G1-phase exit during development and tumorigenesis [16]. p27Kip1 is predominantly regulated via posttranslational mod

  2020-11-06

  

  Prenylation may turn a flavonoid from an agonist to an antagonist and improve the selectivity to both ERs depending on the position of the substitution. C-8 prenylation appears to promote antagonism to a larger extent than C-6 in ERα due to steric hindrance against generation of agonistic conformati

  Binding affinity was measured by a scintillation proximity binding assay using [H]4-OHT (ERRγ) or [H]estradiol (ERα/β) as radioligand. In all cases, the ERβ affinity was not significantly different from ERα. Compounds were compared to , which showed high affinity for both receptors and moderate (six

  Results Discussion The ubiquitin system has in recent years become an exciting area for drug discovery (Cohen and Tcherpakov, 2010), as multiple enzymatic steps within the ubiquitylation process are druggable. The potential of targeting the ubiquitin-proteasome pathway was first demonstrated i

  Increasing evidence supports that the B-cell lymphoid malignancies develop from various stages of B-cells, hijacking the mechanisms that drive B-cell differentiation and activation [27]. For instance, mantle cell lymphoma (MCL) and chronic lymphocytic leukemia (CLL) originate from the pre-germinal c

  2020-11-06

  

  Protein degradation via UPP involves two steps. One step is the conjugation of multiple ubiquitin to a substrate. The other step is the degradation of tagged protein by the downstream 26S proteasome complex. Protein ubiquitination is the E1–E2–E3 enzymatic cascade (Hershko & Ciechanover, 1998). E1-a
