    • IHC image of CSB-RA197122A0HU diluted at 1:50 and staining in paraffin-embedded human kidney tissue performed on a Leica BondTM system. After dewaxing and hydration, antigen retrieval was mediated by high pressure in a citrate buffer (pH 6.0). Section was blocked with 10% normal goat serum 30min at RT. Then primary antibody (1% BSA) was incubated at 4°C overnight. The primary is detected by a Goat anti-rabbit polymer IgG labeled by HRP and visualized using 0.47% DAB.

After dewaxing and hydration, antigen retrieval was mediated by high pressure in a citrate buffer (pH 6.0). Section was blocked with 10% normal goat serum 30min at RT. Then primary antibody (1% BSA) was incubated at 4°C overnight. The primary is detected by a Goat anti-rabbit polymer IgG labeled by HRP and visualized using 0.47% DAB.
    • Immunofluorescence staining of Hela with CSB-RA197122A0HU at 1:5, counter-stained with DAPI. The cells were fixed in 4% formaldehyde and blocked in 10% normal Goat Serum. The cells were then incubated with the antibody overnight at 4°C. The secondary antibody was Alexa Fluor 512-congugated AffiniPure Goat Anti-Rabbit IgG(H+L).
    • Overlay Peak curve showing MCF-7 cells stained with CSB-RA197122A0HU (red line) at 1:50. The cells were fixed in 4% formaldehyde and permeated by 0.2% TritonX-100. Then 10% normal goat serum to block non-specific protein-protein interactions followed by the antibody (1µg/1*106cells) for 45min at 4℃. The secondary antibody used was FITC-conjugated Goat Anti-rabbit IgG(H+L) at 1:200 dilution for 35min at 4℃.Control antibody (green line) was rabbit IgG (1µg/1*106cells) used under the same conditions. Acquisition of >10,000 events was performed.

  • 功能：
    Regulatory subunit of the cAMP-dependent protein kinases involved in cAMP signaling in cells. Type II regulatory chains mediate membrane association by binding to anchoring proteins, including the MAP2 kinase.

    1. High PK-R2 expression is associated with colorectal cancer. PMID: 26372733
    2. Prkar2a deficiency predisposes to hematopoietic malignancies in vivo. RIIalpha's likely association with HS and DLBCL was hitherto unrecognized and may lead to better understanding of these rare neoplasms. PMID: 26608815
    3. Disruption of Snapin-PKR2 interaction did not affect PKR2 signaling, but increased the ligand-induced degradation, implying a role of Snapin in the trafficking of PKR2. PMID: 26687946
    4. we demonstrate that neurochondrin has strong isoform selectivity towards the RIIa subunit of PKA with nanomolar affinity PMID: 25916936
    5. These data demonstrate that some Kallmann syndrome-associated, intracellularly retained mutant PKR2 receptors can be functionally rescued, suggesting a potential treatment strategy for patients bearing such mutations. PMID: 24753254
    6. Smad4 and the R subunit of the protein kinase A holoenzyme form a functional complex in vivo in response to TGFbeta. PMID: 23362281
    7. ETO nervy homology region (NHR) 3 domain-PKA(RIIalpha) protein interaction does not appear to significantly contribute to AML1-ETO's ability to induce leukemia. PMID: 20708017
    8. findings indicate that increased particulate type II protein kinase A activity occurs throughout pregnancy therefore directing the cAMP quiescence signal to specific subcellular loci within myometrial smooth muscle cells PMID: 12727975
    9. These data implicate the involvement of PKA-RIIalpha anchoring apical targeting of distinct proteins and glycosphingolipids to apical plasma membrane domains and suggest that rerouting may underlie the delayed Golgi-to-apical surface transport of MDR1. PMID: 16723498
    10. The high-resolution crystal structures of the docking and dimerization (D/D) domain of the RIIalpha regulatory subunit of PKA in complex with the high-affinity anchoring peptide AKAP-IS explain the molecular basis for AKAP-regulatory subunit recognition. PMID: 17081989
    11. The data suggest that centrosomal anchoring of RIIalpha and the interrelated subapical positioning of these centrosomes is required for oncostatin M-, but not cAMP-mediated, bile canalicular lumen development. PMID: 17494870
    12. RIIalpha releases Calpha upon elevated cAMP alone, dependent on autophosphorylation of the RIIalpha inhibitory domain PMID: 17884635
    13. Bacillus anthracis edema toxin altered the protein levels and activity of protein kinase A and exchange protein activated by cAMP (Epac), a recently identified cAMP-binding molecule. PMID: 19307216
