• The attachment of ubiquitin to RTKs such as EGFR

  2021-04-02

  

  The attachment of ubiquitin to RTKs, such as EGFR, mediates efficient delivery through the endosome-lysosome system for proteolysis. In this way, RTK degradation enables cessation of signal transduction. A recent siRNA screen identified a number of USPs that can significantly modulate EGFR levels an

  2021-04-02

  

  Downregulation of tumor suppressors is a major factor that leads to tumorigenesis. Phosphatase and tensin homolog deleted on chromosome 10 (PTEN), a common tumor suppressor, the Gemcitabine of which is often downregulated or even absent in the majority of human cancers, functions as a phosphatase to

  2021-04-02

  

  How does an increase in E2 affinity for the RING domain favor higher activity and polyubiquitination by the E2? Binding of the RING domain to the E2 positions the donor Ub in the E2~Ub conjugate in a closed complex [16], [17], [18] that increases the reactivity of the thioester [60]. A higher affini

  Deubiquitination, deubiquitinases and cancer Protein deubiquitination is reverse process of ubiquitination and performed by deubiquitinases or deubiquitinating enzymes (DUBs), which help in removal of ubiquitin from target proteins and involve in ubiquitin maturation, recycling and editing (Pfoh

  2021-04-02

  

  Our ex vivo analysis demonstrates that IL-15 promotes CD122 expression in DGKζ-deficient CD8+ T cells. CD122, which forms a dimer with CD132 in response to IL-2 or IL-15, activates the JAK/STAT and PI3K/mTOR pathways. Whereas antigen-stimulated Temozolomide promote IL-2 sensitivity through up-regul

  Conflicts of interest Introduction Diacylglycerols (DAGs) and phosphatidic MK 886 (PA) play fundamental roles in biology as basic components of membranes, intermediates in lipid metabolism, and secondary messengers in cellular signaling (Carrasco and Merida, 2007, Fang et al., 2001). Cells re

  2021-04-02

  

  Proteins that associate to PCNA are characterized by having conserved motifs as the PCNA-interacting protein (PIP) motif [29,30], its variant PIP-like motif [31,32] or the APIM motif (Alk B homologue 2 PCNA interacting motif [33,34]); for instance, p21 contains a PIP motif [30], and DNA polymerases

  Three-dimensional conformational changes in the cargo protein’s NES, caused by protein phosphorylation, dephosphorylation, or mutation, can regulate CRM1 binding (Craig et al., 2002, Vogt et al., 2005). Additional protein modifications such as sumoylation, ubiquitination, acetylation, and/or the bin

  Introduction Angiotensin II (Ang II) and Endothelin 1 (ET-1) are potent vasoconstrictive peptides recognized as key players in many cardiovascular diseases [1]. Cardiac hypertrophy, ischemic arrhythmia, and stroke have been associated to an overstimulation of the angiotensin II type 1 (AT1) recepto

  The Lysine429 mutant is located in the tail region of 5-HT2A, which is predicted to be unstructured. This region has been shown to interact, in vitro, with PSD95 and leads to differences in signaling (Xia et al., 2003). The ASK motif, a component of the tail region, is also important for regulation

  DNA-PK After sensing and binding to the DSB, Ku quickly recruits DNA-PKcs to the site of the DNA break. Similar to Ku70/80, recruitment of DNA-PKcs to DSBs occurs within seconds of their creation [12]. The interaction between Ku70/80 and DNA-PKcs requires the presence of dsDNA and the complex for
