Selective cell-permeable peptide inhibitor of protein kinase C (IC50 ~ 0.5 μM). Consists of amino acids 19 - 31 of PKC pseudosubstrate domain linked by a disulphide bridge to a cell permeabilisation Antennapedia domain vector peptide. The Antennapedia pep
Inhibitor of protein kinase C (PKC) ζ; attached to cell permeabilisation Antennapedia domain vector peptide. Consists of amino acids 113 - 129 of PKC ζ pseudosubstrate domain linked by a disulphide bridge to the Antennapedia domain vector peptide. The Antennapedia peptide is actively taken up by intact cells, at 4 or 37°C, ensuring rapid and effective uptake of the inhibitor peptide. Once inside the cell, the disulphide bonds are subjected to reduction in the cytoplasm leading to release of the inhibitor peptide. Induces mast cell degranulation by a PKC ζ-independent pathway.
Protein Kinase C (19-31) TFA 是蛋白激酶 C (PKC)的抑制剂,是由 PKCa (残基 19-31) 伪底物调控域衍生而来,25 位丝氨酸取代野生型丙氨酸作为蛋白激酶 C 底物肽,用于检测蛋白激酶 C 的活性。Protein kinase C (PKC) TFA 通过磷酸化丝氨酸和苏氨酸氨基酸残基上的羟基来调控其它蛋白的功能。
Myelin Basic Protein (MHP4-14) TFA 是一种合成肽,包含髓鞘碱性蛋白的残基4-14,是一种非常有选择性的 PKC 底物 (Km=7 μM)。Myelin Basic Protein TFA 不被环腺苷酸依赖性蛋白激酶、酪蛋白激酶 I 和 II、Ca2+/钙调素依赖性蛋白激酶 II 或磷酸化酶激酶磷酸化,可常规用于测定粗组织提取物中低背景的蛋白激酶 C。
