Nav1.3

Nav1.3 is a type of sodium channel found in nerve cells. These channels are proteins embedded in the cell membrane that allow sodium ions to enter the neuron. This process is essential for generating electrical signals, such as nerve impulses. Nav1.3 is especially important during nerve development and in response to nerve injury, where it helps with nerve regeneration or, in some cases, contributes to pain signals. It is one of several sodium channel types, each with specific roles in how nerves communicate and respond to stimuli.
