    • KAPCB_HUMAN
    • PKA C beta
    • PKA C-beta
    • PKACB
    • Prkacb
    • protein kinase A catalytic subunit beta

  • Function

    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.

  • Tissue specificity

    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.

  • Sequence similarities

    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.

  • Post-translational
    modifications

    Asn-3 is partially deaminated to Asp giving rise to 2 major isoelectric variants, called CB and CA respectively.

  • Cellular localization

    Cytoplasm. Nucleus. Translocates into the nucleus (monomeric catalytic subunit) (By similarity). The inactive holoenzyme is found in the cytoplasm.
  • Information by UniProt

Question

PKA beta (catalytic subunit) protein (Active) (ab60837)

I have not been able to get the enzyme to phosphorylate a known substrate that I have made, i have tried several conditions as theproduct information sheet doesn't specify the best assay conditions. I am not sure whether the problem is with the enzyme or the substrate - do you sell/can you recommend a substrate that I can use as a control for PKA?

Answer

Thank you for contacting us.

I am sorry to hear you are experiencing difficulties with one of our products. We take product complaints very seriously, and investigate every product that we feel may not be performing correctly.

I contacted the source of this protein and they would liketo receivedetailed information with regards to your protocol, substrate information, lot number.
They need to have a thorough understanding of whathas beenperformed prior to make recommendations
This information will also allow us to investigate this case internally and initiate additional testing where necessary. If the product was purchased in the last six months and is being used according to our Abpromise, we would be happy to replace or refund the protein.

I look forward to receiving your reply.

Answer

Thank you for your inquiry.

I can confirm that ab60837 was used in a kinase assay with CREBtide synthetic peptide substrate (KRREILSRRPSYR) , stock 1mg/ml.

This is available for purchase from other sources.

I attached the kinase assay protocol for your information.

Please let me know if the problems persist with the positive control.

We are happy to confirm that this product is tested and guaranteed for activity assays. In the event that a product is not functioning as stated on the datasheet, we happily offer technical help and a free of charge replacement or credit note.
