A Novel Missense WFS1 Variant: Expanding the Mutational Spectrum Associated with Nonsyndromic Low-Frequency Sensorineural Hearing Loss

Figure 5

Subcellular localization of wild-type (WT) and mutated WFS1. Immunofluorescence staining was performed after transient transfection in HEK-293 cells and HEI-OC1 cells. Images display DAPI in blue, endoplasmic reticulum-specific marker Calnexin in green, Flag-tagged protein in red, and merged pictures. In both HEK-293 cells and HEI-OC1 cells, the variant protein was located in the cytoplasmic endoplasmic reticulum as in the WT. Scale bars =30 μm.
