- TGF-B Receptor I (RI) phosphorylation of Smad2/3 does all of the following EXCEPT: activate Smad2/3 binding to the Co-Smad Smad4 dissociate intramolecular binding of Smad2/3 MH1 and MH2 domains. RI phosphorylation of Smad2/3 does all of these things. release Smad2/3 from the nucleus into the cytoplasm unmask the Smad2/3 nuclear localization signal (NLS).Tumor necrosis factor (TNF) signaling Explain in detail each step in figure 8.53. Make sure to include an explanation of the proteolytic and phosphorylation cascades.The white blood cells known as T lymphocytes respond to antigens thatbind specifi cally to the T cell receptor, which consists of an antigen-binding αβ transmembrane protein as well as a set of transmembrane signaltransducing proteins known as CD3 that are targets of NRTKs. Thecytoplasmic domains of the CD3 proteins are positively charged and, in the absence of antigen, interact with the intracellular surface of the plasma membrane in such a way that buries several of their Tyr residues in the lipidbilayer. Antigen binding to the T cell receptor leads to a localized infl ux ofCa2+ ions. (a) Explain how a high concentration of Ca2+ could promote phosphorylation and activation of the CD3 proteins. (b) Would this henomenon make the T lymphocyte more or less responsive to the antigen?

O They are both down-regulated by lysosomal degradation They both involve receptor exoplasmic domain dimerization They both result in an effector protein entering the nucleus O They both involve cytosolic domain phosphorylationInnate lymphoid cells (ILCS) , implicated in tissue repair and maintenance of barrier integrity, are present in large numbers in the intestine which is also innervated by intestinal nervous system (ENS). Reccent research has shown that ILCS- express receptors for IgG express receptors for neuropeptides and neurotransmitters O function through pattern recognition receptors (PRRS) such as TLRS
- An SH2-containing protein contains a mutation that changes its binding pocket such that tyrosine and phosphotyrosine bind with equal affinity. As a result, MEK activity: does not change with receptor dimerization and transautophosphorylation decreases due to changes in Raf activation increases with ligand binding-induced dimerization decreases due to allosteric inhibition of SH2-domain bindingN-term N- ER Signal Sequence Part of BHCC Protein N-terminus Middle of Protein C-terminus 19a.

Which of the following would lead to a significant loss of cardiac myocytes? Select all that apply Treatment of rapamycin which results in inhibition of mTOR activity Prolonged or severe ER stress with increased accumulation of unfolded proteins Activation of AMPK and phosphorylation of the TSC1 complex mTOR activation and phosphorylation of Ulk1The affinity of integrins for matrix components canbe modulated by changes to their cytoplasmic domains:a process known as inside-out signaling. You have iden-tified a key region in the cytoplasmic domains of αIIbβ3integrin that seems to be required for inside-out signaling(Figure Q19–3). Substitution of alanine for either D723in the β chain or R995 in the α chain leads to a high levelof spontaneous activation, under conditions where thewild-type chains are inactive. Your advisor suggests thatyou convert the aspartate in the β chain to an arginine(D723R) and the arginine in the α chain to an aspartate(R995D). You compare all three α chains (R995, R995A,and R995D) against all three β chains (D723, D723A, andD723R). You find that all pairs have a high level of sponta-neous activation, except D723 vs R995 (the wild type) andD723R vs R995D, which have low levels. Based on theseresults, how do you think the αIIbβ3 integrin is held in itsinactive state?
