Mapping the structural requirements in the CB1 cannabinoid receptor transmembrane helix II for signal transduction.
Amino acid residues in the transmembrane domains of the CB(1) receptor are important for ligand recognition and signal transduction. We used site-directed mutagenesis to identify the role of two novel and adjacent residues in the transmembrane helix II domain, Ile2.62 and Asp2.63. We investigated the role of the conserved, negatively charged aspartate at position 2.63 in cannabinoid receptor (C...
متن کاملSignal transduction of IL-6, leukemia-inhibitory factor, and oncostatin M: structural receptor requirements for signal attenuation.
Stimulation of the IL-6R complex leads to Src homology domain containing tyrosine phosphatase 2 (SHP2) recruitment to the receptor subunit gp130 and its subsequent tyrosine phosphorylation. SHP2 is a two-SH2 domain-containing protein tyrosine phosphatase that is activated by many cytokines and growth factors. SHP2 counteracts the activation of transcription factors of the STAT family and the in...
متن کاملStructural basis of signal transduction in the TNF receptor superfamily.
Members of the tumor necrosis factor receptor superfamily play key roles in innate and adaptive immunity. Here, we review recent structural studies in the intracellular signal transduction of these receptors. A central theme revealed from these structural studies is that upon ligand binding, multiple intracellular proteins form higher-order signaling machines to transduce and amplify receptor a...
متن کاملStructural mechanism for signal transduction in RXR nuclear receptor heterodimers
A subset of nuclear receptors (NRs) function as obligate heterodimers with retinoid X receptor (RXR), allowing integration of ligand-dependent signals across the dimer interface via an unknown structural mechanism. Using nuclear magnetic resonance (NMR) spectroscopy, x-ray crystallography and hydrogen/deuterium exchange (HDX) mass spectrometry, here we show an allosteric mechanism through which...
