PARK7/DJ-1 Protein, Human (GST)

Cat. No.: HY-P71625
COA Handling Instructions

The multifunctional PARK7/DJ-1 protein plays a key role in cellular defense against oxidative stress and cell death. It acts as an oxidative stress sensor, redox-sensitive chaperone and protease, and participates in neuroprotective mechanisms by stabilizing NFE2L2 and PINK1 proteins. PARK7/DJ-1 Protein, Human (GST) is the recombinant human-derived PARK7/DJ-1 protein, expressed by E. coli , with N-GST labeled tag. The total length of PARK7/DJ-1 Protein, Human (GST) is 188 a.a., with molecular weight of ~46.8 kDa.

Description

It acts as an oxidative stress sensor, redox-sensitive chaperone and protease, and participates in neuroprotective mechanisms by stabilizing NFE2L2 and PINK1 proteins. PARK7/DJ-1 Protein, Human (GST) is the recombinant human-derived PARK7/DJ-1 protein, expressed by E. coli , with N-GST labeled tag.

Background

PARK7/DJ-1, a multifunctional protein, assumes a pivotal role in cellular defense against oxidative stress and cell death, functioning as an oxidative stress sensor, redox-sensitive chaperone, and protease. It engages in neuroprotective mechanisms, stabilizing NFE2L2 and PINK1 proteins, positively regulating the androgen signaling pathway for male fertility, and modulating cell growth and transformation through its impact on the NF-kappa-B signaling pathway. Despite its disputed role as a protein and nucleotide deglycase, implicated in repairing glycated proteins and nucleotides, PARK7/DJ-1's involvement in a nucleotide repair system named guanine glycation repair (GG repair) is recognized, mitigating damage caused by methylglyoxal and glyoxal. Acting on early glycation intermediates, it prevents the formation of advanced glycation endproducts (AGE) that inflict irreversible damage. Beyond its role in glycation repair, PARK7/DJ-1 maintains mitochondrial morphology and function, facilitates autophagy of dysfunctional mitochondria, regulates expression or stability of mitochondrial uncoupling proteins, and orchestrates protective responses in pancreatic islets. Moreover, it exerts control over inflammatory responses in astrocytes, modulates endocytosis, binds to specific mRNAs, and exhibits metal-binding capabilities, enhancing cellular defense mechanisms against metal toxicity.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.

  • Reconstitution Calculator

  • Dilution Calculator

  • Specific Activity Calculator

The reconstitution calculator equation

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration
= ÷

The dilution calculator equation

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
× = ×

The specific activity calculator equation

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)
Unit/mg = 106 ÷ ng/mL
