常规说明
c-AMP-dependent Protein Kinase (PKA) is a serine/threonine kinase that regulates a number of cellular processes including proliferation, ion transport and gene transcription. PKA is composed of conserved catalytic subunits and regulatory subunits that dissociate upon activation by cAMP. The catalytic subunit of PKA contains the activation loop and mediates DNA binding and substrate recognition. The catalytic subunit is assembled and expressed as an active form and is phosphorylated on threonine 197 by PDK 1 in the activation loop and serine 338 in the carboxyl terminus. Phosphorylation of serine 338 plays a key role in stabilizing PKA and activating its substrates, and hence mediating its biological functions.
Reproducibility is key to advancing scientific discovery and accelerating scientists’ next breakthrough.
Abcam is leading the way with our range of recombinant antibodies, knockout-validated antibodies and knockout cell lines, all of which support improved reproducibility.
We are also planning to innovate the way in which we present recommended applications and species on our product datasheets, so that only applications & species that have been tested in our own labs, our suppliers or by selected trusted collaborators are covered by our Abpromise™ guarantee.
In preparation for this, we have started to update the applications & species that this product is Abpromise guaranteed for.
We are also updating the applications & species that this product has been “predicted to work with,” however this information is not covered by our Abpromise guarantee.
Applications & species from publications and Abreviews that have not been tested in our own labs or in those of our suppliers are not covered by the Abpromise guarantee.

纯化说明
The antibody has been negatively preadsorbed using a non-phosphopeptide corresponding to the site of phosphorylation to remove antibody that is reactive with non-phosphorylated PKA. The final product is generated by affinity chromatography using a PKA-derived peptide that is phosphorylated at serine 338. -

功能
Mediates cAMP-dependent signaling triggered by receptor binding to GPCRs. PKA activation regulates diverse cellular processes such as cell proliferation, the cell cycle, differentiation and regulation of microtubule dynamics, chromatin condensation and decondensation, nuclear envelope disassembly and reassembly, as well as regulation of intracellular transport mechanisms and ion flux. -
组织特异性
Isoform 1 is most abundant in the brain, with low level expression in kidney. Isoform 2 is predominantly expressed in thymus, spleen and kidney. Isoform 3 and isoform 4 are only expressed in the brain. -
序列相似性
Belongs to the protein kinase superfamily. AGC Ser/Thr protein kinase family. cAMP subfamily.
Contains 1 AGC-kinase C-terminal domain.
Contains 1 protein kinase domain. -
翻译后修饰
Asn-3 is partially deaminated to Asp giving rise to 2 major isoelectric variants, called CB and CA respectively. -
细胞定位
Cytoplasm. Nucleus. Translocates into the nucleus (monomeric catalytic subunit) (By similarity). The inactive holoenzyme is found in the cytoplasm. - Information by UniProt

Western blot - Anti-PKA beta (catalytic subunit) (phospho S338) antibody (ab5816)Peptide Competition: Lysates prepared from 3T3-L1 cells were resolved by SDS-PAGE on a 10% polyacrylamide gel and transferred to PVDF. Membranes were either treated with lambda phosphatase (1) or left untreated (2-5), blocked with a 5% BSA-TBSTbuffer for two hours at room temperature, and incubated with ab5816 antibody for two hours at room temperature in a 3% BSA-TBST buffer, following prior incubation with: no peptide (1, 2), the non-phosphopeptide corresponding to the immunogen (3), a generic phosphoserine-containing peptide (4), or, the phosphopeptide immunogen (5). After washing, membranes were incubated with goat F(ab’)2 anti-rabbit IgG HRP-conjugate and bands were detected using the Pierce SuperSignalTM method. The data show that the peptide corresponding to PKA cat beta [pS338] blocks the antibody signal, thereby verifying the specificity of the antibody. The data also show that phosphatase stripping eliminates the signal, verifying that the antibody is phospho-specific.
