Expression and localization of the inwardly rectifying potassium channel Kir7.1 in native bovine retinal pigment epithelium.

PURPOSE The purpose of this study was to identify the molecular basis of the apical membrane K(+) conductance in native bovine retinal pigment epithelium (RPE). METHODS RT-PCR, Northern blot, and Western blot analyses were used to detect the expression of the inwardly rectifying K(+) (Kir) channel subunits Kir7.1 and Kir4.1 in native bovine RPE and neural… (More)
