Peripherin is a type III Intermediate filament (IF) protein expressed mainly in neurons of the peripheral nervous system (PNS). It is also found in neurons of the central nervous system (CNS) that have projections toward peripheral structures such as spinal motor neurons. Its size structure and sequence/location of protein motifs is similar to other type III IF proteins such as desmin vimentin and glial fibrillary acidic protein (GFAP).
