Research Abstract

Renal K secretion is mediated by the collecting duct cell, and apical ROMK K channels are responsible for this secretion. Although regulation of the ROMK K channel activity has been examined by many reserachers, precise mechanisms for channel expression to the apical membrane is still unknown. In this study, we investigated the expresssion mechanisms using exogeneously transfected cloned ROMK K channels to cultured M-1 kidney cells. Channel expression was observed with fluorescent microscope and channel current was examined using the patch-clamp technique. As the results, expression of ROMK to the apical membrane requred no PDZ domain in the membrane, but other membanes required PDZ domain to express ROMK K channels. Since ROMK K channels are expressed only to the apical membrane but not the basolateral membrane in vivo, it is suggested that ROMK K channels are selectively expressed to the apical membrane in the epithelial cells which may possesses no ROMK-PDZ domain in the membrane.
