SPG21 Human
Spastic Paraplegia 21 Human Recombinant
Catalog No. PRO-677

Synonyms:
MAST, ACP33, GL010, BM-019, MASPARDIN, SPG21, Spastic paraplegia 21 autosomal recessive Mast syndrome protein, Acid cluster protein 33.

Introduction:
SPG21 binds to the hydrophobic C-terminal amino acids of CD4 which take part in suppression of CD-4 dependant T cell activation. The interaction with CD4 is mediated by the noncatalytic alpha/beta hydrolase fold domain. SPG21 adapts the stimulatory activity of CD4. SPG21 is broadly expressed in diverse tissues including heart, brain, placenta, lung, liver, skeletal muscle, kidney and pancreas. Mutations in SPG21 cause Mast syndrome, an autosomal-recessive complicated form of hereditary spastic paraplegia characterized by dementia, thin corpus callosum and white matter abnormalities.

Description:
SPG21 produced in E.Coli is a single, non-glycosylated polypeptide chain containing 328 amino acids (1-308 a.a.) and having a molecular mass of 94.4 kDa.
SPG21 is expressed with a 20 amino acid His tag at N-Terminus and purified by proprietary chromatographic techniques.

Source:
Escherichia Coli.

Physical Appearance:
Sterile filtered colorless solution.

Formulation:
The SPG21 protein solution contains 20mM Tris-HCl, pH-8.

Stability:
Store at 4°C if entire vial will be used within 2-4 weeks.
Store, frozen at -20°C for longer periods of time.
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Avoid multiple freeze-thaw cycles.

Purity:
Greater than 95.0% as determined by SDS-PAGE.
