Tat-Beclin 1 L11S Peptide - Scrambled Control Summary

Tat-L11S [NBP2-49887]: inactive/scrambled control peptides derived from Tat-L11. These peptides are recommended as a negative control. The exact sequence of Tat-Beclin 1 L11S is YGRKKRRQRRRGGNWAWHDFVHIT (Bio-Techne's exclusive patent license: US Patent 8,802,633)
Cell-penetrating autophagy inducing peptides engineered in 2013 were demonstrated to induce autophagy through interaction with the autophagy suppressor GAPR-1/GLIPR2 (Nature, 2013; PMID 23364696). These Tat-Beclin 1 peptides were comprised of AA 267-284 of the autophagy inducer Beclin 1 (18 amino acids), a diglycine linker, and 11 amino acids of the HIV Tat protein transduction domain. Tat-B...eclin 1 peptides were re-engineered to remove 7 AA from the beclin 1 domain. These shorter peptides, Tat-D11 [NBP2-49888] and Tat-L11 [NBP2-49886], demonstrate enhanced autophagy inducing function over the original Tat-Beclin 1 peptides and the inactive/scrambled control peptide Tat-L11S [NBP2-49887]. Tat-D11 and Tat-L11 are potent autophagy inducers which function both in vitro and in vivo to specifically induce autophagy while Tat-L11S is useful as a negative control. Tat-D11 and Tat-L11 peptides are comprised of 11 amino acids of the autophagy-inducing region of beclin 1 fused to the HIV Tat protein. Both Tat-D11 and Tat-L11 peptides function by binding the negative regulator of autophagy GAPR-1/GLIPR2. Upon peptide binding, beclin 1 bound to GARP-1 is released, resulting in beclin 1 mediated autophagosome formation and autophagy induction. Data indicate Tat-D11 is more potent than both Tat-L11 and Tat-Beclin 1 in vivo. In addition, initial data derived from HeLa cells also suggests Tat-D11 is more potent than Tat-L11 in vitro. However, ongoing experiments indicate Tat-L11 may be more potent than Tat-D11 in select cell lines.

Tat-beclin 1 (L-amino acid) / Tat-Beclin 1 L11 (NBP2-49886) and Tat–beclin 1 (D-amino acid)/Tat-Beclin 1 D11, Retroinverso form (NBP2-49888) along with the control peptide Tat-scrambled (L-amino acid)/Tat-Beclin 1 L11S Peptide, Scrambled Control (NBP2-49887) were tested in-vivo for the induction of autophagy. 6-week-old GFP-LC3 transgenic mice, and normal or CHIKV and WNV Egypt strain virus infected 5-day-old GFP-LC3 mice were injected intra-peritoneally (i.p.) with these Tat-beclin derivative peptides at a dose of 20 mg/Kg body weight (5.3uM/Kg). Brain tissues were analyzed using IHC-Frozen and Western blot analysis for measuring cell death (TUNEL Assay) and p62 expression respectively. Toxicity of these peptides was assessed in 6-day-old C57BL/6J mice via daily injections of Tat-scrambled (L-amino acid, Tat-Beclin 1 L11S) or Tat-beclin 1 (L-amino acid, Tat-Beclin 1 L11) at 15 mg kg-1 and Tat–beclin 1 (D-amino acid, Tat-Beclin 1 D11) at a dose of 20 mg/Kg body weight for 2 weeks (Figure 4).
