Neurensin 1 (NRSN1)

Neurensin-1/Neuro-p24 (previously named Neuro-p24) is a neuron-specific membrane protein that is localized particularly in neurites. Neurensin-1 is considered to play an essential role in neurite extension during nervous development, regeneration and plasticity. In the retinal cell culture from newborn mice, two types of neural cells were stained for Neurensin-1, one of which showed long processes and appeared presumptive ganglion cells.

Neurensin-1 plays a role in the fiber extension of the retinal neurons, as has been observed in other central nervous tissues, and indicate that the developing retina is a suitable experimental model for the analysis of Neurensin function, both in vivo and in vitro.
