From: Ligand-dependent localization and intracellular stability of sigma-1 receptors in CHO-K1 cells
Endogenous Sigma-1 receptors colocalize with other proteins in the FAC. A-C. Colocalization with talin. A-sigma-1; B-talin; C-Overlay. D-F. Colocalization with Kv1.4. potassium channel. D-sigma-1; E-Kv1.4.; F-Overlay. G, H. Colocalization of sigma-1(green) and F-Actin(red) in mock or phalloidin (50 ng/ml for 30 min) treated cells. Note, that the sigma-1 localized on the the barbed ends of actin filaments.
