GDNF signals through a multi-component receptor system, composed of a RET protooncogene and one of the four α1-α4 receptors1.GDNF promotes survival of various neuronal cells, including motoneurons2,3, Purkinje cells and sympathetic neurons4. In embryonic midbrain cultures, GDNF promotes the survival and morphological differentiation of dopaminergic neurons and increases their high-affinity dopamine uptake5. Cells that express GDNF include Sertoli cells, type 1 astrocytes, Schwann cells6, neurons, pinealocytes, and skeletal muscle cells7.In vivo, following transection of facial motor neuron axons, locally applied GDNF has been shown to rescue virtually all damaged neurons from death8. GDNF may be of clinical relevance in the treatment of Parkinson's disease that is characterized by progressive degeneration of midbrain dopaminergic neurons9,10.Recently, it has been hypothesized that functional, carboxy-terminally amidated peptides are processed from the GDNF precursor upon proteolytic cleavage by furin-like endopeptidase11,12,13. Those different peptides (a 5-mer and 11-mer) have not been isolated endogenously to date. However, the rat 11-mer sequence (named brain excitatory peptide, BEP) significantly induced synaptic excitability and possessed some dopaminergic activities in vitro (thus named dopamine neuron stimulating peptides, DNSP)13. Furthermore, the human 11-mer sequence (named DNSP-11) exhibits neurotrophic-like properties13.Thus, the role of the full proDomain of GDNF, which is a product of proteolytic cleavage of proGDNF, is not clearly understood yet.\u003c\/p\u003e \u003ch2\u003eResearch relevance and current trends\u003c\/h2\u003e \u003cul\u003e \u003cli\u003eUsing high-specificity ligands, toxins, and engineered peptides to dissect closely related receptor\/channel subtypes and signaling microdomains.\u003c\/li\u003e\n\u003cli\u003ePairing labeled (e.g., fluorescent) proteins\/peptides with advanced imaging to map surface expression, trafficking, and nanoscale organization.\u003c\/li\u003e\n\u003cli\u003eIncreasing emphasis on reproducibility through standardized characterization (identity, purity, and lot QC) and transparent reporting of reagent attributes.\u003c\/li\u003e \u003c\/ul\u003e \u003ch2\u003eCommon research applications\u003c\/h2\u003e \u003cul\u003e \u003cli\u003eAssay development and optimization: used as a reference material or tool reagent in RUO workflows.\u003c\/li\u003e\n\u003cli\u003eReagent validation: supports conceptual controls such as competition\/neutralization, when relevant.\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003eAcross these use cases, changes in signal or functional readout are generally interpreted as evidence of differences in target abundance, accessibility, or engagement, but alternative explanations (matrix effects, off-target interactions, or assay artifacts) should be considered.\u003c\/p\u003e \u003ch2\u003eNotes for experimental interpretation\u003c\/h2\u003e \u003cul\u003e \u003cli\u003eAssay context matters: binding assays, functional modulation, and detection workflows can yield different readouts even for the same target system.\u003c\/li\u003e\n\u003cli\u003eMatrix and sample effects: buffer composition, detergents, and biological matrices may alter stability or apparent activity; interpret with appropriate controls.\u003c\/li\u003e\n\u003cli\u003eControl concepts: include negative controls and orthogonal validation (e.g., genetic perturbation or alternative reagents) to support robust interpretation.\u003c\/li\u003e \u003c\/ul\u003e \u003c!-- Sources (internal): - UniProt Knowledgebase (UniProtKB) — UniProt Consortium — https:\/\/www.uniprot.org\/ - NCBI Gene — National Center for Biotechnology Information (NCBI) — https:\/\/www.ncbi.nlm.nih.gov\/gene\/ - NCBI Protein — National Center for Biotechnology Information (NCBI) — https:\/\/www.ncbi.nlm.nih.gov\/protein\/ - PubChem — NIH\/NLM\/NCBI — https:\/\/pubchem.ncbi.nlm.nih.gov\/ - IUPHAR\/BPS Guide to Pharmacology — IUPHAR\/BPS — https:\/\/www.guidetopharmacology.org\/ - RCSB Protein Data Bank (PDB) — RCSB PDB — https:\/\/www.rcsb.org\/ - NCBI Bookshelf — NIH\/NLM — https:\/\/www.ncbi.nlm.nih.gov\/books\/ --\u003e","brand":"Alomone Labs","offers":[{"title":"Default Title","offer_id":53073012064621,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/SPG-100_str-1_642.gif?v=1772699875","url":"https:\/\/www.ebiohippo.com\/products\/human-gdnf-prodomain-bhp21300119","provider":"BioHippo","version":"1.0","type":"link"}
