KC1 — Solanum tuberosum

Summary

StKC1 (PGSC0003DMG400040591) on potato chromosome 9 encodes a potassium channel with voltage-sensitive potassium channel activity, Kir channel activity, and identical protein binding. It belongs to the KAT/AKT family and contains KHA, ion transport, and cNMP-binding domains. The gene is associated with potassium uptake, stomatal opening, drought tolerance, and salt tolerance. It is linked to wound healing, TOR signaling, pH reduction, jasmonic acid anabolism, post-translational modification, nitric oxide storage, seed germination, and signal transduction. The product localizes to monoatomic ion channel complexes and the ER membrane. Related genes in other species link the family to potassium transport and stress responses.
