  • Function

    Binds the sequence 5'-ATCAATCAA-3'. Acts as a transcriptional activator of PF4 in complex with MEIS1. Converted into a potent transcriptional activator by the (1;19) translocation. May have a role in steroidogenesis and, subsequently, sexual development and differentiation.
  • Tissue specificity

    Expressed in all tissues except in cells of the B and T lineage.
  • Involvement in disease

    Note=A chromosomal aberration involving PBX1 is a cause of pre-B-cell acute lymphoblastic leukemia (B-ALL). Translocation t(1;19)(q23;p13.3) with TCF3. E2A-PBX1 transforms cells by constitutively activating transcription of genes regulated by PBX1 or by other members of the PBX protein family.
  • Sequence similarities

    Belongs to the TALE/PBX homeobox family.
    Contains 1 homeobox DNA-binding domain.

  • Paraffin-embedded human testis tissue stained for PBX1/PRL using ab236911 at 1/300 dilution in immunohistochemical analysis.

    After dewaxing and hydration, antigen retrieval was mediated by high pressure in a citrate buffer (pH 6.0). Section was blocked with 10% normal goat serum 30 minutes at RT. Then primary antibody (1% BSA) was incubated at 4°C overnight. The primary is detected by a biotinylated secondary antibody and visualized using an HRP conjugated SP system.

  • HeLa (human epithelial cell line from cervix adenocarcinoma) cells stained for PBX1/PRL (green) using ab236911 at 1/100 dilution in ICC/IF. Secondary antibody is Alexa Fluor® 488-conjugated Goat Anti-Rabbit IgG (H+L). The nuclear counter stain is DAPI (blue).

    The cells were fixed in 4% formaldehyde, permeabilized using 0.2% Triton X-100 and blocked in 10% normal Goat Serum. The cells were then incubated with the antibody overnight at 4°C.
