14-3-3 theta Protein, Human (His)

14-3-3 theta proteins are adapters in multiple signaling pathways that recognize phosphoserine or phosphothreonine motifs and modulate chaperone activity upon binding. It negatively regulates PDPK1 kinase activity, forms homodimers, and interacts with CDK16, phosphorylated RGS7, SSH1, phosphorylated CDKN1B, GAB2, phosphorylated PDPK1, and phosphorylated DAPK2. 14-3-3 theta Protein, Human (His) is the recombinant human-derived 14-3-3 theta protein, expressed by E. coli , with N-6His labeled tag.

The 14-3-3 theta protein functions as an adapter implicated in the regulation of a diverse array of both general and specialized signaling pathways, engaging with numerous partners through the recognition of phosphoserine or phosphothreonine motifs. This binding typically results in the modulation of the activity of the interacting partner. Notably, 14-3-3 theta negatively regulates the kinase activity of PDPK1 and forms homodimers. It interacts with CDK16, RGS7 in its phosphorylated form, SSH1, CDKN1B in its 'Thr-198' phosphorylated form, GAB2, the 'Ser-241' phosphorylated form of PDPK1, and the 'Thr-369' phosphorylated form of DAPK2. Additionally, 14-3-3 theta interacts with PI4KB, TBC1D22A, TBC1D22B, SLITRK1, RIPOR2 isoform 2, INAVA (increasing upon pattern recognition receptor stimulation), MARK2, MARK3, MARK4, and MEFV. These interactions underscore the versatile role of 14-3-3 theta in various cellular processes and signaling pathways.

Approximately 29 kDa, based on SDS-PAGE under reducing conditions.

• 
  ≥ 95%, as determined by reducing SDS-PAGE.

Lyophilized powder.

Lyophilized from a 0.22 μm filtered solution of 50 mM Tris-HCl, 300 mM NaCl, pH 7.4.
Note: For SPR assay, please replace the buffer. Primary amine components (e.g., Tris, imidazole) can affect protein-coupled chips.

<1 EU/μg, determined by LAL method.

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH₂O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).

Stored at -20°C for 2 years from date of receipt. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Room temperature in continental US; may vary elsewhere.
