  By using live imaging of an ERK fluorescence resonance energy transfer (FRET) sensor, the authors show that ERK activity propagates in a stepwise manner from the center to the periphery of the tracheal placode. This row-by-row propagation of ERK activity fits a relay model in which each row activate

  2021-08-31

  

  Protein ubiquitination occurs at the lysine residues, and is mediated by the sequential reactions of ubiquitin-activating enzyme (E1), conjugating enzyme (E2), and ligase (E3). The first step in this process comprises the ATP-dependent activation of ubiquitin by E1 to form a ubiquitin–E1 conjugate.

  EBI2 remains an orphan GPCR and the identity and source of its ligand are yet to be described. Molecular studies of EBI2 have suggested that this receptor has constitutive activity, similar to that observed for many herpesvirus-encoded 7TM receptors (Benned-Jensen and Rosenkilde, 2008, Rosenkilde et

  2021-08-30

  

  Taken together, these assays demonstrate that SUMOD positioning is essential for all E3 ligases but dispensable for E2 and S*E2 sumoylation reactions. Thus, we propose SUMOD positioning as a key criterion to describe the enzymatic function of SUMO E3 ligases that distinguishes them from other enhanc

  Introduction BRs are well known class of steroid phytohormones involved in the regulation of key processes of plant growth and development [1], [2], [3], [4], [5]. A lot of attention is driven to BRs in the last decade because of their undeniable functions in promoting smad inhibitor reactions of

  In the course of carbohydrate metabolism, pyruvate, the end product of glycolysis, is converted to acetyl-CoA, which fuels the citrate cycle for further generation of energy. In the case of elevated levels of acetyl-CoA, acetyl-CoA is converted into malonyl-CoA by the action of acetyl-CoA carboxylas

  Rat pheochromocytoma PC12 cells have been widely used as a cell system to study intracellular signaling leading to neurite outgrowth. The advantages of using PC12 cells in the CHK studies are the fact that they naturally express the rat form of CHK and the observation that down-regulation of CHK fun

  Enzyme catalysis A biochemically spontaneous process proceeds in a direction where free RG7388 synthesis of the system decreases. However, every spontaneous or energetically favorable reaction needs to overcome an energy barrier known as the activation energy barrier because of the formation of a

  7α,25-dihydroxycholesterol (7α,25-OHC) was recently identified by classic analytical methods as a high-affinity ligand for EBI2 (Hannedouche et al., 2011; Liu et al., 2011). 7α,25-OHC was previously identified as an intermediate in the alternate pathway of hepatic bile CHIR-124 synthesis (Russell,

  The structure of the HOIP RBR–LDD module bound to UbcH5~Ub reveals insights into an activated HOIP component [47]. Contacts between the E2~Ub and the non-cognate RBR module in the crystal suggest how a structure in which the active sites of the E2 and the E3 are in close proximity might look. In thi

  Introduction O6-Methylguanine-DNA methyltransferase (MGMT) is a DNA-repair enzyme that specifically transfers alkyl adducts from the O6 position of guanine to the cysteine residue (Cys145) in its active site. In cancer cells, this ability of MGMT disrupts the cytotoxic actions of alkylating antic
