Cellular localization and kinetic properties of NaV1.9-, NaV1.8-, and NaV1.7-like channel subtypes in Helix pomatia

▶Localization and distribution of Nav1.9, 1.8, and 1.7 channel subtypes in neurons. ▶Biophysical properties of cells equipped with different sets of Na-channel subtypes. ▶Neurons expressing different Na-channels are responsible for specific functions. ▶Na-channels are similar in vertebrates and gastropods showing a common origin. ▶Na-channels have slow kinetic and low ion selectivity, typical property of gastropods.
