In the specialized field of neurodegenerative research, the study of alpha-synuclein has become a cornerstone for SNCA - Alpha-synuclein - Homo sapiens (Human) understanding the molecular mechanisms underlying various neuropathies. As a researcher frequently sourcing high-quality reagents, I have found that navigating the nuances of alpha synuclein r peptide and related recombinant materials is essential for consistent experimental outcomes.
Defining the Protein and Its Biological Significance
Alpha-Synuclein (α-Synuclein) is a presynaptic protein found to be a major component of Parkinson's Disease (PD) aggregates. It is encoded by the SNCA gene, located on chromosome 4p21, and is processed as a 140 amino ac These preformed fibrils of α-synuclein may be used as a model for the pathogenic form of α-synuclein in numerous neuropathies. id (aa) pr by JW Jin · 2021 · Cited by 44 — The peptide effectively reduced the level of α-synuclein via proteasomal degradation both in cell cultures and in animals. Tat-βsyn-degron otein with a theoretical molecular weight of approximately 14 kD.
Under normal physiological conditions, alpha-synuclein is a soluble protein that plays several roles in synaptic activity, such as the regulation of synaptic vesicle trafficking and subsequent neurotransmitter release. However, its tendency to cycle between a free, partially unfolded form and a helical, membrane-bound form makes it a focal point in amyloid research. When misfolded, it aggregates to form filamentous inclusions, specifically Lewy bodies and Lewy neurites, which are a major component of Lewy bodies in the affected neurons in Parkinson's disease.
Reagents and Experimental Models
For those looking to order Human Alpha Synuclein Monomers (SPR-316) or similar variants, quality control is paramount. rPeptide offers a large selection of Beta Amyloids, Taus, Synucleins, Calmodulins, Custom Products, and more, which are widely utilized in in vitro and in vivo models.
When conducting research, one must distinguish between different forms of the protein:
* Monomers: Recombinant human Alpha-Synuclein protein monomer (1 to 140 aa) is typically expressed in *Escherichia coli* and provided with >95% purity.
* Preformed Fibrils: The preformed fibrils of α-synuclein serve as a critical model for the pathogenic form of α-synuclein in numerous neuropathies, allowing researchers to simulate aggregation pathways in a controlled environment.
* Truncated Variants: Specialized research often requires fragments such as Alpha-Synuclei by B Popova · 2021 · Cited by 21 — Two synthetic peptides, K84s and K102s, of 25 and 19 amino acids, respectively, significantly inhibited αSyn oligomerization and aggregation at sub- n, 61-140, or Alpha-Synuclein, 1-60, to isolate specific binding domains.
Peptide-Based Approaches and Therapeutic Potential
The current efforts made in the development of peptides and their mimetics are among the most exciting frontiers in this domain. Scientists are investigating how a specific peptide can be designed to inhibit the formation of alpha-synuclein aggregates.
For instance, the Tat-βsyn-degron peptide has been documented as a successful tool for inducing the proteasomal degradation of the protein. By utilizing a targeting peptide-based system, researchers have demonstrated the specific knockdown of α-synuclein, effectively reducing its levels in cell cultures and animal models. Furthermore, novel biomimetic peptides are being chemically conjugated to target these aggregates directly, representing a Alpha-Synuclein is normally a soluble protein. Abnormal alpha-synuclein forms filamentous inclusions (Lewy bodies and Lewy neurites) in several promising strategy for modulating the protein's pathological behavior.
