Description

g-Synuclein Human Recombinant produced in E.Coli is a single,non-glycosylated polypeptide chain containing 127 amino acids and having a molecular mass of 13,300 Dalton.
The protein coding region of g-synuclein was amplified by RT-PCR and cloned into an E.coli expression vector. g-synuclein was overexpressed in E. coli and purified to apparent homogeneity by taking advantage of the thermosolubility of the protein and by using conventional column chromatography techniques.

Product Specs

Introduction
Gamma-synuclein, initially known as BCSG1 (breast cancer specific gene product), is a 127-amino acid acidic neuronal protein. It belongs to the synuclein family, believed to be involved in neurodegenerative disease development. Elevated gamma-synuclein levels are found in advanced breast carcinomas, suggesting a link between its overexpression and tumor progression. This protein is primarily located in the peripheral nervous system (sensory, sympathetic, and motor neurons) and the retina. Additionally, it's found in the brain, ovarian tumors, and olfactory epithelium. Gamma-synuclein expression in breast tumors serves as a tumor progression marker. Altered gamma-synuclein expression has been observed in the retina of Alzheimer's patients.
Description
Recombinant human gamma-synuclein, produced in E. coli, is a single, non-glycosylated polypeptide chain comprising 127 amino acids with a molecular weight of 13.3 kDa. The protein's coding region was amplified via RT-PCR and cloned into an E. coli expression vector. Overexpression in E. coli was followed by purification using the protein's thermosolubility and standard column chromatography techniques, achieving apparent homogeneity.
Physical Appearance
A clear, colorless solution that has been sterilized by filtration.
Formulation
The protein solution (1 mg/ml) is prepared in 20 mM Tris-HCl buffer (pH 7.5) containing 0.1 M NaCl.
Stability
For short-term storage (2-4 weeks), the product can be stored at 4°C. For extended storage, freeze at -20°C. Adding a carrier protein (0.1% HSA or BSA) is recommended for long-term storage. Minimize repeated freeze-thaw cycles.
Purity
Purity exceeds 90.0% as determined by SDS-PAGE analysis.

Product Science Overview

Introduction

Gamma-Synuclein, also known as SNCG, is a member of the synuclein family, which includes alpha-synuclein and beta-synuclein. These proteins are small, soluble, and predominantly expressed in neural tissues. Gamma-Synuclein is encoded by the SNCG gene located on chromosome 10q23.2 .

Structure and Expression

Gamma-Synuclein is a presynaptic protein that plays a crucial role in the peripheral nervous system and retina . It is involved in maintaining the integrity of the neurofilament network and modulating axonal architecture during development and in adulthood . The protein consists of 127 amino acids and has a molecular mass of approximately 13,331 Da .

Function and Role in Disease

Gamma-Synuclein is implicated in several neurodegenerative diseases, including Parkinson’s Disease (PD) and other synucleinopathies . It is a major component of pathological aggregates found in these disorders. The protein’s role in disease pathogenesis is linked to its ability to form insoluble fibrils that contribute to neuronal dysfunction and cell death .

Recombinant Gamma-Synuclein

Recombinant human gamma-synuclein is produced using Escherichia coli (E. coli) expression systems. The recombinant protein is purified to ensure high purity and quality, making it suitable for various research applications, including aggregation studies, seeding experiments, and molecular standards . The protein is typically provided in a lyophilized form and can be reconstituted in buffer solutions for experimental use .

Applications in Research

Recombinant gamma-synuclein is widely used in research to study its role in neurodegenerative diseases. It is utilized in experiments to understand the mechanisms of protein aggregation, the formation of pathological inclusions, and the development of potential therapeutic strategies . Additionally, gamma-synuclein is used as a molecular standard in various biochemical assays .
