  • Function

    Transcription factor that binds to the octamer motif (5'-ATTTGCAT-3') and activates the promoters of the genes for some small nuclear RNAs (snRNA) and of genes such as those for histone H2B and immunoglobulins. Modulates transcription transactivation by NR3C1, AR and PGR (By similarity). In case of human herpes simplex virus (HSV) infection, POU2F1 forms a multiprotein-DNA complex with the viral transactivator protein VP16 and HCFC1 thereby enabling the transcription of the viral immediate early genes.
  • Tissue specificity

    Ubiquitous. Isoform 2 is lymphocyte-specific.
  • Sequence similarities

    Belongs to the POU transcription factor family. Class-2 subfamily.
    Contains 1 homeobox DNA-binding domain.
    Contains 1 POU-specific domain.
  • Post-translational

    Phosphorylated by PRKDC.

  • Overlay histogram showing Jurkat cells stained with ab51363 (red line). The cells were fixed with 4% paraformaldehyde (10 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab51363, 1µg/1x106 cells) for 30 min at 22ºC. The secondary antibody used was DyLight® 488 goat anti-mouse IgG (H+L) (ab96879) at 1:500 dilution for 30 min at 22ºC. Isotype control antibody (black line) was mouse IgG1 [ICIGG1] (ab91353, 2µg/1x106 cells) used under the same conditions. Acquisition of >5,000 events was performed. This antibody gave a positive signal in Jurkat cells fixed with 80% methanol (5 min)/permeabilized with 0.1% PBS-Tween for 20 min used under the same conditions.

Thank you for your reply.

In brief, the protocol was: Immunostaining analysis in HeLa cells. HeLa cells were fixed with 4% paraformaldehyde and permeabilized with 0.1% Triton X-100 in PBS. The cells were immunostained with ab51363.


1) Fix cells with 2-4% PFA in PBS for 10 min at RT.
2) Wash cells twice with PBS.
3) Permeabilize cells with 0.1% Triton X-100 in PBS.
4) Wash cells three times with PBS.
5) Block with 10% normal serum.
6) Incubate cells with first antibody in 2% normal serum for 1 hr at RT.
7) Wash cells in BPS three times for 5 min.
8) Incubate cells with secondary antibody in 2% normal serum for 1 hr at RT.
9) Wash cells in PBS three times in 5 min.
10) Mount with mounting medium and seal with nail polish.
