Abstract

We have used the polymerase chain reaction (PCR) with primers against the S5 and S6 regions of voltage-gated K⁺ channels to identify 8 different specific amplification products using poly(A)⁺ RNA isolated from islets of Langerhans from obese hyperglycémic (ob/ob) mice and from the two insulin-producing cell lines HIT T15 and RINmSF. Sequence analysis suggests that they derive from mRNAs coding for a family of voltage-gated K⁺ channels; 5 of these have been recently identified in mammalian brain and 3 are novel. These hybridize in classes to different mRNAs which distribute differently to a number of tissues and cell lines including insulin-producing cells.
