Neuroserpin is a protein that in humans is encoded by the SERPINI1 gene.^[5]

It is associated with Familial encephalopathy with neuroserpin inclusion bodies.

Serine protease inhibitors of the serpin superfamily are involved in many cellular processes. Neuroserpin was first identified as a protein secreted from the axons of dorsal root ganglion neurons (Stoeckli et al., 1989). It is expressed in the late stages of neurogenesis during the process of synapse formation.[supplied by OMIM]^[5]

Interactions

SERPINI1 has been shown to interact with Tissue plasminogen activator.^[6]
