  To function as Ub-ligases, E3 proteins must interact with E2s. As compared to the extensive studies on E3s, functional studies on E2s are relatively rudimentary in higher plants. We previously reported that there are 48 genes encoding Ub-conjugating (UBC) fold-containing putative E2 proteins in the

  Compounds were synthesized using a facile 8-step convergent synthesis ( and ). Briefly, (Boc)cyclen (compound ) was coupled using TBTU to Fmoc- or Cbz-protected amino alkyl acids (–), followed by deprotection using 20% piperidine in DMF, or H on Pd/C, respectively (–) (). Deprotected linkers were co

  The major regulator of radiation sensitivity Tumor cell resistance to radiation is a big issue for radiation therapy, and a major concern of radiation oncologist. Understanding the regulation mechanism of radiation sensitivity is still a research hotspot. Increased sensitivity to ionizing radiati

  UVC-induced DNA damage: a model to study DNA damage tolerance The UV components of sunlight that reaches the Earth surface are one of the most carcinogenic agents humans are exposed to, and the leading cause of skin cancer [4,12]. UV light causes different types of DNA damage through indirect and

  Keeping the cofactor content, oligomeric state, subcellular localization, and membrane association in view, DHODH has been broadly divided into two classes, class 1 and class 2 [26], [27]. In many species it is present to either cytoplasm (Class 1) or to the inner mitochondrial membrane (or plasma

  MTT results show that, both pancreatic cell lines were quite sensitive to camptothecin (CPT), a well known topoisomerase I poison. Interestingly, CPT does not show any selectivity over cancer cell lines probably due to the duplication times for cancerous (MIA PaCa-2) and immortalized healthy (HPDEC)

  A possible explanation for these observations has been provided by a recent study showing that EWS-FLI-1 increases the Skp2-mediated 26S proteasome degradation, decreasing p27 protein stability and preventing cell senescence [42]. Mechanism of action of EWS-FLI-1 Molecular analysis has revealed

  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

  The UPP broadly involves proteolysis in biochemical processes and is a potential target for cancer therapy. The UPP degrades unfolding or damaged proteins by an ATP-dependent mechanism (Ciechanover, Elias, Heller, Ferber, & Hershko, 1980). It also plays an important role in 490 regulation, DNA dama

  At the cellular level, TGF-β1 has been involved in the formation of invadosomes (Mandal et al., 2008, Varon et al., 2006). Invadosomes are actin-based structures involved in matrix degradation and cell invasion through metalloproteinases (MMP) activity (Linder et al., 2011). Invadosomes, constitutiv
