Modulation of Maxi-Calcium-Activated K Channels: Role of Ligands, Phosphorylation, and G-Proteins

  • Chapter
GTPases in Biology II

Part of the book series: Handbook of Experimental Pharmacology ((HEP,volume 108 / 2))

Abstract

Calcium-activated K channels are present in a vast number of tissues, including: brain, skeletal and smooth muscles, epithelia, and secretory glands. They have been classified in terms of their conductance as “maxi” (BK; ≈150-300pS), “intermediate” (IK; ≈100pS), and “small” (SK; <100pS) Ca-activated K (KCa) channels (for review see Latorre et al. 1989; Cook and Young 1990; McManus 1991).
