14-3-3 sigma Protein, Mouse

Cat. No.: HY-P74438
COA Handling Instructions

14-3-3 sigma protein, an adapter in diverse signaling pathways, binds phosphoserine or phosphothreonine motifs, modulating partner activity. It regulates protein synthesis and cell growth via Akt/mTOR pathway stimulation when bound to KRT17. It may also regulate MDM2 autoubiquitination, activating p53/TP53. Existing as a homodimer, it interacts with GAB2, KRT17, SAMSN1, SRPK2, COPS6, COP1 (for degradation), phosphorylated DAPK2, PI4KB, SLITRK1, and LRRK2 (phosphorylation-dependent). Complexes include XPO7, EIF4A1, ARHGAP1, VPS26A, VPS29, and VPS35. 14-3-3 sigma Protein, Mouse is the recombinant mouse-derived 14-3-3 sigma protein, expressed by E. coli, with tag free. The total length of 14-3-3 sigma Protein, Mouse is 248 a.a., with molecular weight of ~32 kDa.

Background

The 14-3-3 sigma protein functions as an adapter implicated in the regulation of a broad spectrum of both general and specialized signaling pathways, engaging with numerous partners through the recognition of phosphoserine or phosphothreonine motifs, thereby modulating the activity of the binding partner. Particularly, when bound to KRT17, it plays a role in regulating protein synthesis and epithelial cell growth by stimulating the Akt/mTOR pathway. Additionally, it may regulate MDM2 autoubiquitination and degradation, leading to the activation of p53/TP53. Existing as a homodimer, 14-3-3 sigma is found in a complex with XPO7, EIF4A1, ARHGAP1, VPS26A, VPS29, and VPS35, and it interacts with various proteins, including GAB2, KRT17, SAMSN1, SRPK2, COPS6, COP1 (leading to proteasomal degradation), the 'Thr-369' phosphorylated form of DAPK2, PI4KB, SLITRK1, and LRRK2 (dependent on LRRK2 phosphorylation). These diverse interactions highlight the versatile role of 14-3-3 sigma in orchestrating various cellular processes and signaling events.

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

  • 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
