  2021-02-23

  

  How does APC/C recognize its substrates and catalyze their ubiquitylation? How are the outcomes and timing of these activities regulated? These questions have driven a decade of structural studies that begin to explain how APC/C interacts with coactivators, substrates, and E2s, and how these interac

  Although our knowledge of the biochemical and biological functions of E3 ubiquitin ligases has increased in B-cell malignancies, a deeper characterization of cell-context dependent substrate regulation and biological relevance is needed.

  Multi-subunit RINGs There are RING-type E3s that exist as multi-subunit assemblies (see Fig. 3B). A striking example is the Cullin RING Ligase (CRL) superfamily [35], which exhibits enormous plasticity in substrate specificity. Each CRL subfamily is characterized by a cullin protein (Cul-1, 2, 3,

  2021-02-23

  

  Mulan is a mitochondrial protein and is exclusively localized in the OMM with its RING domain facing the cytosol [14]. Based on this topology, Mulan can provide a link between molecular events in the mitochondria and cytoplasm. Mulan has been implicated in various processes including: mitochondrial

  The BMP family comprises significant growth factors for the regeneration of bone and cartilage. Among these, BMP- has been known as an early marker during the proliferation of osteoblast cells, and one of the most potent stimulators of osteoblastic cells differentiation [40].

  The presence of H+-PPases in parasitic protists raises the question of the physiological role of these proteins. So far, they had been extensively characterized mainly in higher plants, and some prokaryotes [1], [2], [3], [4], [5], [6], [7], [16], [20]. A common feature to all these organisms is tha

  The all-α NTP pyrophosphatase and NUDIX families maintain the deoxynucleotide triphosphate (dNTP) pool balance, limit the incorporation of harmful nucleotides, and represent a promising therapeutic approach to develop anticancer and immunosuppressive agents., , , , Among these housekeeping enzymes i

  In the present study, we combined activity-based protein profiling, biochemical and genetic approaches to identify the PLCPs involved in the sphingolipid pathway leading to plant PCD. By using Arabidopsis LLY507 and leaves, we demonstrate that this sub-class of plant proteases is activated in respo

  Genotype-phenotype correlations Genotype-phenotype correlations are limited. Compared with individuals with truncating variants, those with pathogenic missense variants in the adenosine triphosphate binding site had a milder disorder, some with ability to walk unaided, better hand use, and less r

  We further examined our hypothesis that the activation of CRF and CCK systems is responsible for the enhanced anxiety-like behavior induced by immobilization stress using two antagonists to block the expression of CRF1 and CCK2 receptors. It was found that CCK2 receptor antagonist CR2945 or CRF1 ant

  Another option is to use the thiol groups of cysteine residues, which can be modified by use of PEG-maleimide and vinyl sulfone. However, changes in PEGylation interactions or reaction conditions can result in changes in the functional properties of the therapeutic proteins [[50], [51], [52]]. A st

  It is now known that cholinergic signaling plays a vital role in controlling many peripheral functions including skeletal and smooth muscle contraction, autonomic postganglionic neuron activation, parasympathetic end-organ activation (e.g., salivary, lacrimal and bronchial glands), regulation of car
