Calmodulin-Dependent Protein Kinase II (290-309) is a potent CaMK antagonist with an IC50 of 52 nM for inhibiting Ca2+/calmodulin-dependent protein kinase II.
Calmodulin-Dependent Protein Kinase II (281-309) is a synthetic peptide phosphorylatable at Thr286 by PKC, inhibiting CaM kinase II with an IC50 of 80 nM.
[Ala286]-Calmodulin-Dependent Protein Kinase II (281-302) 是CaMKII活性区域的一段,经特别设计,在第286位点上的丙氨酸替代增强了其结构.这一修饰使得[Ala286]-Calmodulin-Dependent Protein Kinase II (281-302) 成为开发更高效CaMKII抑制剂的理想候选.
Two Rho-associated kinases (ROCK), ROCK-I and ROCK-II, act downstream of the G protein Rho to regulate cytoskeletal stability. The ROCKs play important roles in diverse cellular functions including cell adhesion and proliferation, smooth muscle contraction, and stem cell renewal. Glycyl-H-1152 is a selective and potent ROCK inhibitor (IC50 = 11.8 nM for ROCK-II). It is a glycylated isoquinoline compound derived from the therapeutically-important ROCK inhibitor HA-1077 (Fasudil) and exhibits better specificity. Thus, it poorly inhibits Ca2+/calmodulin-dependent kinase type II, protein kinase (PK) G, and Aurora A (IC50 = 2.57, 2.35, and 3.26 μM, respectively) as well as PKA or PKC (IC50 ≥ 10 μM for each). The potency of Glycyl-H-1152 is superior to that of other ROCK inhibitors, including Y-27632 (Ki = 220 nM) and HA-1077 (IC50 = 158 nM).
12(S)-HpETE(12-羟基二十碳四烯酸)是花生四烯酸在12-脂氧合酶(12-LOX)作用下生成的过氧化代谢产物。能剂量依赖性地刺激细胞内Ca2+释放(效用低于12-HETE),还能通过其对内皮细胞的作用参与血管张力的调节,诱导血管平滑肌细胞c-Fos和c-Jun蛋白的表达,增加AP-1( activating protein 1)的活性。
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。
Autocamtide-2 is a highly selective peptide substrate for calcium/calmodulin-dependent protein kinase II (CaMKII), which belongs to the CAMK Ser/Thr protein kinase family.
