Basolateral Potassium Channel (Intestinal)

Molecular classification
Ion channel, Potassium channel, KCa channel, KCNN family, KCNK family, KCNJ family, KCNQ family
01

Overview

Basolateral potassium channels in intestinal epithelial cells are crucial for maintaining electrolyte and fluid homeostasis. They facilitate potassium efflux from the cell into the interstitial space, supporting nutrient absorption, chloride secretion, and membrane potential maintenance. KCa3.1 (KCNN4) is a prominent subtype in human colonocytes. Dysfunction is linked to gastrointestinal disorders like IBD-associated diarrhea. Pharmacological agents like clotrimazole can modulate their activity, affecting wound healing and inflammatory responses.
