WB 1/250. Detects a band of approximately 81 kDa (predicted molecular weight: 91 kDa).

Target

  • Function

    Hydrolyzes the second messenger cAMP, which is a key regulator of many important physiological processes.
  • Tissue specificity

    Widespread; most abundant in skeletal muscle. Isoform 6 is detected in brain. Isoform 8 is detected in brain, placenta, lung and kidney. Isoform 7 is detected in heart and skeletal muscle.
  • Pathway

    Purine metabolism; 3',5'-cyclic AMP degradation; AMP from 3',5'-cyclic AMP: step 1/1.
  • Involvement in disease

    Note=Genetic variations in PDE4D might be associated with susceptibility to stroke. PubMed:17006457 states that association with stroke has to be considered with caution.
  • Sequence similarities

    Belongs to the cyclic nucleotide phosphodiesterase family. PDE4 subfamily.
  • Post-translational
    modifications

    Isoform 3 and isoform 7 are activated by phosphorylation (in vitro), but not isoform 6. Isoform N3 and isoform 12 are phosphorylated on Ser-49, Ser-51, Ser-55 and Ser-59.
  • Cellular localization

    Cytoplasm. Membrane. Cytoplasm > cytoskeleton. Cytoplasm > cytoskeleton > centrosome. Found in the soluble fraction, associated with membranes, and associated with the cytoskeleton and the centrosome.

    Developed using the ECL technique.

    Performed under reducing conditions.

    Predicted band size: 91 kDa
    Observed band size: 81 kDa
    why is the actual band size different from the predicted?
    Additional bands at: 28 kDa, 70 kDa. We are unsure as to the identity of these extra bands.


    Exposure time: 20 minutes


    The predicted molecular weight of Human cAMP-specific 3',5'-cyclic phosphodiesterase 4D is 71 kDa(SwissProt), however we expect to observe a banding pattern at 81 kDa. Abcam welcomes customer feedback and would appreciate any comments regarding this product and the data presented above.
  • ICC/IF image of ab87329 stained HeLa cells. The cells were 4% PFA fixed (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab87329, 5µg/ml) overnight at +4°C. The secondary antibody (green) was Alexa Fluor® 488 goat anti-rabbit IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM. This antibody also gave a positive result in 100% methanol fixed (5 min) HeLa cells at 5µg/ml.

Customer reviews and Q&As

Answer

Thank you for contacting us. I apologise for the delay, I wanted to check this case with my lab colleagues.
Regarding ab59249, the amino acid range of this immunogen is aaXXXX of human PDE4D with accession# Q08499 (http://www.uniprot.org/uniprot/Q08499).
This antibody binds to isoforms 4, 3, 5, N3, 8, 9, 7, and 12. It does not bind to isoform 10, 1, 2, and 6. According to the isoforms that this antibody binds, you would expect to see two bands, approximately 25 and 85 kDa. Because the western blot on our website is cut off at 34 kDa, we can retest this antibody to see if it does actually bind the lower isoform as well.
Although we haven’t specifically tested the antibody against all isoforms, there are other alternatives that may also recognise several forms of the protein:
For ab77080 we ran a BLAST search and found the antigen sequence in all of 9 isoforms:
https://www.abcam.com/PDE4D-antibody-ab77080.html
Ab112018 also shares 100% identity to isoforms PDE4D1-9:
https://www.abcam.com/PDE4D-antibody-ab112018.html
Ab99409 and ab87329 recognize 10 of 12 isoforms listed for SwissProt entry Q08499. The two isoforms listed for SwissProt Q08499 not recognized by either of them are sp|Q08499-7|PDE4D_HUMAN and sp|Q08499-12|PDE4D_HUMAN:
http://www.uniprot.org/uniprot/Q08499
And ab87329’s immunogen is present in 8 out of 12 of them so it should detect isoforms 1- 10.
I hope this information is helpful to you. Please do not hesitate to contact us if you need any more advice or information.
