Peripherin[edit]
Peripherin is a type of intermediate filament protein that is primarily expressed in the peripheral nervous system. It plays a crucial role in the development and maintenance of neurons, particularly in the axons of sensory neurons and motor neurons.
Structure[edit]
Peripherin is a member of the type III intermediate filament protein family. It shares structural similarities with other intermediate filament proteins, such as vimentin, desmin, and glial fibrillary acidic protein (GFAP). The protein is encoded by the PRPH gene, which is located on chromosome 12 in humans.
Function[edit]
Peripherin is involved in the formation of the cytoskeleton in neurons. It contributes to the stability and integrity of the axons, facilitating the proper transmission of nerve impulses. Peripherin is also implicated in the regeneration of nerve fibers following injury, making it a protein of interest in neurodegenerative disease research.
Expression[edit]
Peripherin is predominantly expressed in the peripheral nervous system, but it can also be found in certain regions of the central nervous system. Its expression is regulated during neuronal development and is upregulated in response to nerve injury.
Clinical Significance[edit]
Mutations or dysregulation of peripherin have been associated with various neurological disorders. For instance, abnormal peripherin aggregation has been observed in amyotrophic lateral sclerosis (ALS) and other motor neuron diseases. Research is ongoing to understand the role of peripherin in these conditions and its potential as a therapeutic target.
