| Specificity / Sensitivity | PKA C-α Antibody detects endogenous levels of total PKA C-α. |
| Source / Purification | Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to the carboxy terminal sequence of human PKA C-α. Antibodies are purified by protein A and peptide affinity chromatography. Western Blotting
Western blot analysis of extracts from HeLa, C6, PC12 and NIH/3T3 cells, using PKA C-α Antibody. Western Blotting
Western blot analysis of extracts from HeLa cells transfected with non-targeted (-) or PKA C-α (+) siRNA. PKA C-α was detected using the PKA C-α Antibody #4782, and Akt1 was detected using Akt1 (2H10) Monoclonal Antibody #2967. The PKA C-α Antibody confirms silencing of PKA C-α expression, and the Akt1 Antibody is used to control for loading and specificity of PKA C-α siRNA. Western Blotting
Western blot analysis of extracts from HeLa cells, transfected with either 100 nM SignalSilence® Control siRNA (Fluorescein Conjugate) #6201 (-), SignalSilence® PKA C-α siRNA II (+) or SignalSilence® PKA C-α siRNA I #6406 (+), using PKA C-α Antibody #4782 and α-Tubulin (11H10) Rabbit mAb #2125. The PKA C-α antibody confirms silencing of PKA C-α expression and α-Tubulin (11H10) Rabbit mAb is used to control for loading and specificity of PKA C-α siRNA. Flow Cytometry
Flow cytometric analysis of HeLa cells, using PKA C-α Antibody (blue) compared to a nonspecific negative control antibody (red). IF-IC
Confocal immunofluorescent analysis of HeLa cells using PKA C-alpha Antibody (green). Actin filaments have been labeled with DY-554 phalloidin (red). Blue pseudocolor = DRAQ5™ (fluorescent DNA dye). |
| Background | The second messenger cyclic AMP (cAMP) activates cAMP-dependent protein kinase (PKA or cAPK) in mammalian cells and controls many cellular mechanisms such as gene transcription, ion transport, and protein phosphorylation (1). Inactive PKA is a heterotetramer composed of a regulatory subunit (R) dimer and a catalytic subunit (C) dimer. In this inactive state, the pseudosubstrate sequences on the R subunits block the active sites on the C subunits. Three C subunit isoforms (C-α, C-β, and C-γ) and two families of regulatory subunits (RI and RII) with distinct cAMP binding properties have been identified. The two R families exist in two isoforms, α and β (RI-α, RI-β, RII-α, and RII-β). Upon binding of cAMP to the R subunits, the autoinhibitory contact is eased and active monomeric C subunits are released. PKA shares substrate specificity with Akt (PKB) and PKC, which are characterized by an arginine at position -3 relative to the phosphorylated serine or threonine residue (2). Substrates that present this consensus sequence and have been shown to be phosphorylated by PKA are Bad (Ser155), CREB (Ser133), and GSK-3 (GSK-3α Ser21 and GSK-3β Ser9) (3-5). In addition, combined knock-down of PKA C-α and -β blocks cAMP-mediated phosphorylation of Raf (Ser43 and Ser259) (6). Autophosphorylation and phosphorylation by PDK-1 are two known mechanisms responsible for phosphorylation of the C subunit at Thr197 (7).

zhanghai123 大家好！我最近在做一种GPCR的信号通路的分析 目前能够确定的是我的这种受体在我所用的细胞系中是与Gαi相偶联，以前公认是与Gq相偶联， 然后我用H89处理细胞，确定PKA 参与其中的调控。 可是，我用环腺苷酸环化酶抑制剂SQ22536处理，却没有发现能够干预这条通路。 目前公认的PKA是cAMP依赖的一种激酶，可是现在的结果却是矛盾的。 我想问一下大家：是否存在不依赖cAMP的PKA的活化方式
又称依赖于cAMP的蛋白激酶A (cyclic-AMP dependent protein kinase A)，是一种结构最简单、生化特性最清楚的蛋白激酶。 PKA全酶分子是由四个亚基组成的四聚体, 其中两个是调节亚基(regulatory subunit, 简称R 亚基)，另两个是催化亚基(catalytic subunit, 简称 C 亚基)。R亚基的相对分子质量为49～55kDa, C亚基的相对分子质量为40kDa,总相对分子质量约为180kDa；全酶没有
