Inhibition of the Kv4 (Shal) family of transient K+ currents by arachidonic acid.
We have found that transient A-type currents expressed in Xenopus oocytes from members of the Kv4 family are suppressed by arachidonic acid. Currents from members of the Kv1, Kv2, and Kv3 families showed little or no inhibition by fatty acids in this expression system, although Shaker currents showed a modest increase in peak amplitude. The inhibition of Kv4 channels was not prevented by cyclo-...

Homology model and targeted mutagenesis identify critical residues for arachidonic acid inhibition of Kv4 channels
Polyunsaturated fatty acids such as arachidonic acid (AA) exhibit inhibitory modulation of Kv4 potassium channels. Molecular docking approaches using a Kv4.2 homology model predicted a membrane-embedded binding pocket for AA comprised of the S4-S5 linker on one subunit and several hydrophobic residues within S3, S5 and S6 from an adjacent subunit. The pocket is conserved among Kv4 channels. We ...
