Overview
This gene encodes a cytoskeletal protein found in neurons of the peripheral nervous system. The encoded protein is a type III intermediate filament protein with homology to other cytoskeletal proteins such as desmin, and is a different protein that the peripherin found in photoreceptors. Mutations in this gene have been associated with susceptibility to amyotrophic lateral sclerosis. -

What is PRPH protein?
PRPH (peripherin) gene is a protein coding gene which situated on the long arm of chromosome 12 at locus 12q13. This gene encodes a cytoskeletal protein found in neurons of the peripheral nervous system. The encoded protein is a type III intermediate filament protein with homology to other cytoskeletal proteins such as desmin, and is a different protein that the peripherin found in photoreceptors. The PRPH protein is consisted of 470 amino acids and its molecular mass is approximately 53.7 kDa.
What is the function of PRPH protein?
PRPH is a cytoskeletal protein that is widely expressed in the nervous system. It interacts with the microtubules and intermediate filaments of nerve cells to help maintain the shape and structure of nerve cells. It plays a key role in the axon growth and branch formation of nerve cells, and is involved in the development and differentiation of nerve cells.
PRPH Related Signaling Pathway
In the neurotrophic factor signaling pathway, neurotrophic factors such as brain-derived neurotrophic factor (BDNF) can influence the expression and distribution of PRPH, thereby regulating the growth and differentiation of neurons. PRPH plays a key role in axon formation and maintenance. It interacts with a variety of cytoskeletal and motor proteins and is involved in axon growth and stability. In some cases, PRPH interacts with apoptosis-related proteins, affecting the survival of neurons.
PRPH Related Diseases
The PRPH protein is a cytoskeletal protein that is widely expressed in the nervous system. It is associated with a variety of neurological diseases, especially peripheral neuropathy. Its abnormal expression or absence is associated with a variety of peripheral neuropathies, such as Charcot-Marie-Tooth disease (CMT). ALS is a progressive neurodegenerative disease that causes motor neurons to gradually lose function. Abnormal expression of the PRPH protein in ALS patients is thought to be associated with the progression of the disease. And multiple neuritis.
Bioapplications of PRPH
Exploring how PRPH expression or function is regulated could lead to a better understanding of the pathogenesis of these diseases, potentially providing new strategies for treating nerve damage or disease. Because of PRPH's important role in the nervous system, it is also used as a tool for drug screening and evaluation, helping researchers identify drugs with potential therapeutic effects on the nervous system.

Case Study 1: Todd M Doran, 2016
A major goal in understanding autoimmune diseases is to define the antigens that elicit a self-destructive immune response, but this is a difficult endeavor. In an effort to discover autoantigens associated with type 1 diabetes (T1D), the researchers used epitope surrogate technology that screens combinatorial libraries of synthetic molecules for compounds that could recognize disease-linked autoantibodies and enrich them from serum. Autoantibodies from one patient revealed a highly phosphorylated form of peripherin, a neuroendocrine filament protein, as a candidate T1D antigen. Peripherin antibodies were detected in 72% of donor patient sera. Further analysis revealed that the T1D-associated antibodies only recognized a dimeric conformation of peripherin. These data explain why peripherin was dismissed as an important T1D antigen previously. The discovery of this novel autoantigen would not have been possible using standard methods, such as hybridizing serum antibodies to recombinant protein arrays, highlighting the power of epitope surrogate technology for probing the mechanism of autoimmune diseases.

Case Study 2: Jesse McLean, 2010
Peripherin is a type III intermediate filament protein that is up-regulated during neuronal injury and is a major component of pathological inclusions found within degenerating motor neurons of patients with amyotrophic lateral sclerosis (ALS). The relationship between these inclusions and their protein constituents remains largely unknown. Here, the researchers profile peripherin isoform expression and ratio changes in traumatic neuronal injury, transgenic mouse models of motor neuron disease, and ALS. Extensive western blot analyses of Triton X-100 soluble and insoluble fractions of neuronal tissue from these conditions revealed significant changes in peripherin isoform content which could be differentiated by electrophoretic banding patterns to produce distinct peripherin biochemical signatures. Significantly, they found that the pattern of peripherin expression in ALS most closely approximates that of peripherin over-expressing mice, but differs with regard to inter-individual variations in isoform-specific expression.

Q&As (6)
Ask a questionThere are currently no drugs that directly target PRPH protein, but there are some drugs that can affect its expression level and activity, such as some growth factors and cytokines.
PRPH protein, as the rhodopsin of retinal photoreceptor cells, can sense light stimulation and convert light signals into electrical signals through the G protein-coupled receptor signal transduction pathway, which is then transmitted to the brain to form vision.
Its role in physiological and pathological processes can be studied by specifically knocking out the PRPH gene using specific short hairpin RNA or zinc finger nuclease technology.
There are currently some studies that report specific PRPH inhibitors that can inhibit the enzymatic activity of PRPH and thus exert therapeutic effects.
Protein may play a protective role in retinopathy, and changes in its expression levels may be related to the occurrence and progression of retinopathy.
Specific PRPH inhibitors may also have a therapeutic effect on other neurological diseases, such as multiple sclerosis and Alzheimer's disease.
