  • Application notes
    Is unsuitable for IHC-P or IP.
  • Target

    • Function

      Constitutively inactive PPiase, which becomes active when bound to calmodulin and calcium. Seems to act as a chaperone for BCL2, targets it to the mitochondria and modulates its phosphorylation state. The BCL2/FKBP8/calmodulin/calcium complex probably interferes with the binding of BCL2 to its targets. The active form of FKBP8 may therefore play a role in the regulation of apoptosis.
    • Tissue specificity

      Widely expressed. Highest levels seen in the brain.
    • Sequence similarities

      Contains 1 PPIase FKBP-type domain.
      Contains 3 TPR repeats.
    • Cellular localization

      Mitochondrion membrane.

      Lanes 1 - 4: Merged signal (red and green). Green - ab129113 observed at 51 kDa. Red - loading control, ab18058, observed at 124 kDa.

      ab129113 was shown to specifically react with FKBP38 when FKBP38 knockout samples were used. Wild-type and FKBP38 knockout samples were subjected to SDS-PAGE. ab129113 and ab18058 (loading control to Vinculin) were diluted 1/1000 and 1/10000 respectively and incubated overnight at 4°C. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preadsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye® 680RD) preadsorbed (ab216776) secondary antibodies at 1/10000 dilution for 1 hour at room temperature before imaging.
