DNA-PK Substrate 是一种有生物活性的肽。(DNA 依赖性蛋白激酶 (DNA-PK) 磷酸化的底物。 DNA-PK 对于修复 DNA 双链断裂至关重要。该肽对应于人 p53 的 11-24 个氨基酸，其中苏氨酸 18 和丝氨酸 20 更改为丙氨酸，用作 DNA-PK 活性测定的底物。当谷氨酰胺 (Q) 或谷氨酸时，可能会自发形成焦谷氨酰 (pGlu) 肽(E) 位于序列 N 末端。 Q或E向pGlu的转化是自然发生的，并且一般认为pGlu的疏水性γ-内酰胺环可能在针对胃肠道蛋白酶的肽稳定性中发挥作用。因此，焦谷氨酰肽被认为是此类肽的正常子集，并在 HPLC 分析期间作为肽纯度的一部分包含在内。)

生物活性

DNA-PK Substrate is a biological active peptide. (A substrate for DNA-dependent protein kinase (DNA-PK), phosphorylation. DNA-PK is essential for the repair of DNA double-strand breaks. This peptide corresponding to 11–24 amino acids of human p53 with threonine 18 and serine 20 changed to alanine is used as a substrate for the assay of DNA-PK activityPyroglutamyl (pGlu) peptides may spontaneously form when either Glutamine (Q) or Glutamic acid (E) is located at the sequence N-terminus. The conversion of Q or E to pGlu is a natural occurrence and in general it is believed that the hydrophobic γ-lactam ring of pGlu may play a role in peptide stability against gastrointestinal proteases. Pyroglutamyl peptides are therefore considered a normal subset of such peptides and are included as part of the peptide purity during HPLC analysis.)

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.
