Lypd6 Interacts with Lrp6 and Partitions into Ordered Membrane Domains in Giant Plasma Membrane Vesicles (A) spGFP-Lypd6 and spGFP-Lypd6ΔGPI-CD44 TMD coIP with Lrp6-HA, but not with Ldlr-HA, in HEK293T cells. spGFP-Lypd6ΔGPI does not coIP with Lrp6-HA or Ldlr-HA. (B) spGFP-Lypd6 coIPs with Flag-xFz8 in HEK293T cells, and this binding is strongly enhanced by Wnt3a. Flag-xFz8 also binds to Lrp6-HA, which is enhanced by Wnt3a, but does not bind to Ldlr-HA. Lypd6 and Lrp6 still bind to Fz8 when expressed together. (C–E) Partitioning of various GFP-tagged Lypd6 constructs in giant plasma membrane vesicles (GPMVs) derived from CHO cells. Fast DiI marks the disordered compartments. See also Figure S4. |
