  • Function

    This is a calcium-independent, phospholipid-dependent, serine- and threonine-specific enzyme. Phosphorylates 'Ser-311' of RELA subunit of NF-kappa-B.
    PKC is activated by diacylglycerol which in turn phosphorylates a range of cellular proteins. PKC also serves as the receptor for phorbol esters, a class of tumor promoters. Subunit of a quaternary complex that plays a central role in epithelial cell polarization.
  • Tissue specificity

    Expressed in brain, and to a lesser extent in lung, kidney and testis.
  • Sequence similarities

    Belongs to the protein kinase superfamily. AGC Ser/Thr protein kinase family. PKC subfamily.
    Contains 1 AGC-kinase C-terminal domain.
    Contains 1 OPR domain.
    Contains 1 phorbol-ester/DAG-type zinc finger.
    Contains 1 protein kinase domain.
  • Domain

    The OPR domain mediates mutually exclusive interactions with SQSTM1 and PARD6B.
    The C1 domain does not bind the diacylglycerol (DAG).
  • Post-translational

    CDH5 is required for its phosphorylation at Thr-410.
  • Cellular localization

    Cytoplasm. Endosome. Cell junction. In the retina, localizes in the terminals of the rod bipolar cells (By similarity). Associates with endosomes. Presence of KRIT1, CDH5 and RAP1B is required for its localization to the cell junction.

  • Immunoprecipitation.
    Rat renal cortex from adult male Sprague-Dawley CD rats was isolated and suspended in CelLyticTM MT Mammalian Tissue Lysis/Extraction reagent containing complete protease inhibitor mixture. Tissues were then homogenized and centrifuged at 2,500 x g for 10 minutes at 4 °C. The supernatant was used for immunoprecipitation. To eliminate nonspecific binding, 1 ml of rat kidney lysate (3 mg of protein) was pre-cleared by incubation with 50µl of TrueBlotTM anti-rabbit Ig IP beads overnight at 4 °C. Cleared cell lysates were incubated with either 7µg of ab4137 or 1µg of polyclonal rabbit anti-rOAT3 for 2 hours at 4 °C. TrueBlot anti-rabbit Ig IP beads (30µl) was added and incubation was continued for 2 hours at 4 °C. Bound proteins were washed 7 times with increasing washing stringency IP buffers and eluted from beads by heating in 4 x NuPAGE LDS sample buffer for 10 minutes. The Invitrogen NuPAGE Novex Tris

Thank you for your patience and for providing details regarding your protocol. Ab4137 was characterized for use in Western blotting with rat brain and myeloid tissues. This antibody has not yet been tested for cross-reactivity with human samples. I would therefore recommend using rat brain or myeloid tissue as a positive control. The antibody is predicted to react with other mammals due to sequence homology, but this hasn't been tested so we cannot guarantee results. The originator of this antibody also mentioned that the calculated molecular weight is 67.7 kDa but it is common to find that the protein resolves closer to 76-80 kDa. I know that you mentioned seeing a band at approximately 50 kDa, but try the antibody again with a positive control (also, make sure that there are sufficient protease inhibitors in your sample buffer). I hope this helps, please contact us again if you need additional assistance.

Thank you for your enquiry. Did you try increasing the concentration of the primary to 1:100? Please let me know if that improved your results. What specifically are the rat samples that you are using? Can you tell me as well, how did you store the antibody? Thanks again, and I look forward to hearing from you.
