Distinct cellular expression and subcellular localization of Kv2 voltage-gated K + channel subtypes in dorsal root ganglion neurons conserved between mice and humans.

The subcellular distribution of Kv2 voltage-gated potassium channels enable compartment-specific modulation of membrane excitability and organization of membrane contact sites. Here we identify subcellular distributions of the Kv2 paralogs, Kv2.1 and Kv2.2, in somatosensory neurons that bear similarities to and distinctions from central neurons. The distribution of Kv2 channels is similar in mouse and human somatosensory neurons. These results identify unique locations of Kv2 channels in somatosensory neurons that could enable roles in sensory information processing.
