KC1 — Daucus carota subsp. sativus

Summary

DcKC1 (DCAR_003919) on carrot chromosome 1 encodes a voltage-sensitive potassium channel with Kir channel activity and identical protein binding capability, belonging to the KAT/AKT family and containing a cyclic nucleotide-binding domain. The gene is associated with somatic embryogenesis and embryogenesis, and its product localizes to the monoatomic ion channel complex and ER membrane. DcKC1 is associated with responses to drought, salinity, and abscisic acid (ABA) signaling, as well as broader abiotic stress responses and hormone signaling pathways. Studies of related genes in other species connect the family to potassium uptake and stress tolerance, though these functions are not yet established for DcKC1 itself.
