We have shown that three components contribute to functional voltage gated K+ (K v) currents in rat small mesenteric artery myocytes: (1) Kv1.2 plus Kv1.5 with Kvβ1.2 subunits, (2) Kv2.1 probably associated with Kv9.3 subunits, and (3) Kv7.4 subunit

Multiple K v channel complexes contribute to total K v current in numerous cell types and usually subserve different physiological functions. Identifying the complete compliment of functional K v channel subunits in cells is a prerequisite to underst

Background Enhanced function of dihydropyridine-sensitive Ca2+ channels (CaV) in hypertensive arterial myocytes (HAM) is well accepted. Increased protein expression of pore forming α1-subunits contributes to this effect, but cannot explain all of th

Alternative splicing of the voltage-gated Ca2+(CaV) α1-subunit adds to the functional diversity of Ca2+channels. A variant with a 73-nt deletion in exon 15 of the Cav1.2 α1-subunit (Cav1.2Δ73) produced by alternative splicing that predicts a trunc

A gain of function mutation N588K in the KCNH2 gene that encodes HERG channels has been shown to underlie the SQT1 form of short QT syndrome (SQTS). We describe a different mutation in the KCNH2 gene in a Chinese family with clinical evidence of SQTS

Background We have previously demonstrated differences in the gene expression of voltage-gated K v1.X channel alpha-subunits in arteries from Wistar-Kyoto rats (WKYs) and spontaneously hypertensive rats (SHRs). The purpose of this study was to test t
