Internexin
Internexin
Internexin (pronounced in-ter-neks-in) is a type of protein that is encoded in humans by the INA gene. It is a neuronal intermediate filament protein that is expressed in a wide variety of neuronal cells and tissues.
Etymology
The term "Internexin" is derived from the Latin words "inter", meaning between, and "nexin", which is a term used in biochemistry to refer to a type of protein. The name reflects the protein's role as an intermediate filament in neuronal cells.
Function
Internexin plays a crucial role in the formation and maintenance of the cytoskeleton in neuronal cells. It is involved in the process of neurogenesis, the growth and development of nerve tissue. It is also associated with the transport of materials within cells, a process known as axonal transport.
