Dynamics of TREM2-TMH wild-type and the K186A variant.Figure 3(a,b) Generalized order parameter S2 for backbone amide resonances derived from NMR relaxation experiments with wild-type TREM2-TMH (a) and the K186A variant (b), indicative of motions in the nanosecond to picosecond time scale. S2 can adopt values between 1 (rigid) and 0 (unrestricted motion). Error bars have been obtained by a Monte-Carlo-simulation-based error estimation and motional model selection procedure implemented in the software Relax (c,d) Molecular dynamics simulations of TREM2-TMH wt (c) and K186A (d) in a POPC/POPG (3:1) bilayer provide information on the stability of helix insertion into a lipid bilayer membrane. Since K186 is initially located in the hydrophobic membrane, its positively charged side chain is pulled towards the negatively charged phosphates in the lipid head group region leading to a pronounced tilt in helix orientation in the nanosecond time scale and on a µ-second to milli-second time scale to a kink in the C-terminal half of the α-helix, as probed by NMR line broadening. In contrast, in the K186A variant the transmembrane helix is stably inserted within the bilayer.
Figure 5 Schematic describing the co-incubation and co-expression experiments used to demonstrate ERdj3 co-secretion with destabilized TTR. For co-incubation, HEK293T cells overexpressing flag-tagged TTR variants were seeded with an equal number of cells overexpressing ERdj3. For co-expression experiments, HEK293T cells are transfected with both flag-tagged TTR and ERdj3. TTR was immunoisolated with M2 anti-FLAG beads from media conditioned overnight on the cells, eluted and separated by SDS-PAGE for immunoblotting.
