| 产品名称: | Protein Kinase C [19-35] Peptide |
| 产品链接: | http://www.abbiotec.com/peptides/protein-kinase-c-%25255B19-35%25255D-peptide%2525C2%2525A0 |
| 货号: | 350009 |
| 规格: | 1 mg |
| 产品描述: | This peptide corresponds to the residues 19-35 of the pseudosubstrate domain of protein kinase C isoforms alpha and beta. The peptide is a potent inhibitor of both the phosphorylation of protein kinase C substrates (Ki = 147 nM) and the autophosphorylation of protein kinase C whereas it has a low inhibitory activity on protein kinase A (IC50 = 423 mM). |
| 序列: | Arg-Phe-Ala-Arg-Lys-Gly-Ala-Leu-Arg-Gln-Lys-Asn-Val-His-Glu-Val-Lys or RFARKGALRQKNVHEVK |
| 分子式: | C89H153N33O22 |
| 分子量: | 2037.4 g/mol |
| 纯度: | Purity > 95% by HPLC |
| 别名: | Protein kinase C alpha type; PKC-alpha; PKC-A; PRKCA; PKCA; PRKACA; Protein kinase C beta type; PKC-beta; PKC-B; PRKCB1; PKCB; PRKCB |
| 形态: | Each vial contains 1 mg of lyophilized solid packaged under an inert gas and supplied as a trifluoroacetate salt. |
| 溶解方法: | Distilled water for a solution up to 2 mg/ml, otherwise we recommend using acetonitrile. |
| 保存方法: | Store at -20°C. The product is hygroscopic and must be protected from light. Product is guaranteed one year from the date of shipment. Following reconstitution, aliquot and store at -20°C. |

文献和实验Analysis of Protein Kinase C Function
Protein kinase C is a key element in signal transduction, cell regulation, and tumor promotion, influencing cellular responses to many stimuli at a variety of levels, including receptors, transduction systems, ion channels, and membrane pumps
蛋白激酶C是G蛋白偶联受体系统中的效应物, 在非活性状态下是水溶性的,游离存在于胞质溶胶中,激活后成为膜结合的酶。蛋白激酶C的激活是脂依赖性的,需要膜脂DAG的存在,同时又是Ca2 依赖性的,需要胞质溶胶中Ca2 浓度的升高。当DAG在质膜中出现时,胞质溶胶中的蛋白激酶C被结合到质膜上,然后在Ca2 的作用下被激活。 同蛋白激酶A一样,蛋白激酶C属于多功能丝氨酸和苏氨酸激酶。蛋白激酶C能激活细胞质中的靶酶参与生化反应的调控, 同时也能作用于细胞核中的转录
PKC系统(protein kinase C system,PKC system)
( diacylglycerol, DAG)和1,4,5-三磷酸肌醇(IP3)。IP3动员细胞内钙库释放Ca2 到细胞质中与钙调蛋白结合,随后参与一系列的反应;而DAG在Ca2 的协同下激活蛋白激酶C(protein kinase C,PKC),然后通过蛋白激酶C引起级联反应,进行细胞的应答, 故此将该系统称为PKC系统,或称为IP3、DAG、Ca2 信号通路。
