  • Function
    May affect the structure or silencing of chromatin by phosphorylating HP1 gamma/CBX3. Isoform 2 promotes the G1/S transition of the cell cycle via up-regulation of CDK2 activity and phosphorylation of CDKN1B, resulting in enhanced nuclear export and proteasome-dependent degradation of CDKN1B. Isoform 2 also represses CDKN1B transcription by phosphorylating and inactivating the transcription factor FOXO3. Plays a role in signal transduction in blood cells. Contributes to both cell proliferation and survival and thus provides a selective advantage in tumorigenesis.
  • Tissue specificity
    Expressed primarily in cells of the hematopoietic and germline lineages. Isoform 1 and isoform 2 are both expressed in prostate cancer cell lines.
  • Sequence similarities
    Belongs to the protein kinase superfamily. CAMK Ser/Thr protein kinase family. PIM subfamily.
    Contains 1 protein kinase domain.
  • Post-translational
    Autophosphorylated on both serine/threonine and tyrosine residues.
  • Cellular localization
    Cytoplasm. Nucleus and Cell membrane.

  • Lane 1: Wild-type HAP1 cell lysate (20 µg)
    Lane 2: PIM1 knockout HAP1 cell lysate (20 µg)
    Lane 3: K562 cell lysate (20 µg)
    Lane 4: Jurkat cell lysate (20 µg)
    Lanes 1 - 4: Merged signal (red and green). Green - ab54503 observed at 35 kDa. Red - loading control, ab181602, observed at 37 kDa.
    ab54503 was shown to recognize PIM1 when PIM1 knockout samples were used, along with additional cross-reactive bands. Wild-type and PIM1 knockout samples were subjected to SDS-PAGE. ab54503 and ab181602 (loading control to GAPDH) were  diluted 3 μg/mL and 1/2000 and incubated overnight at 4°C. Blots were developed with Goat anti-Mouse IgG H&L (IRDye® 800CW) preadsorbed (ab216772) and Goat Anti-Rabbit IgG H&L (IRDye® 680RD) preadsorbed (ab216777) secondary antibodies at 1/10000 dilution for 1 h at room temperature before imaging.

  • Anti-PIM1 antibody [ZP003] (ab54503) at 3 µg/ml + K562 cell lysate

    Observed band size: 35 kDa (why is the actual band size different from the predicted?)
