Anti -Pbx1

For Research Use Only. Not for use in diagnostic procedures.

Chromosome: 1; NC_000001.10 (164528802..164821045). Location: 1q23

Monoclonal

IgG1

8D105

Mouse

Recognizes human PBX1.

Affinity Purified
Purified using Protein G column chromatography from culture supernatant of hybridoma cultured in a medium containing bovine IgG-depleted (~95%) fetal bovine serum.

Supplied as a liquid in PBS, 7.4, 1% BSA and 0.05% sodium azide.

May be stored at 4 degree C for short-term only. For long-term storage and to avoid repeated freezing and thawing, add sterile glycerol (40-50%), aliquot and store at -20 degree C. Aliquots are stable for at least 12 months at -20 degree C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.

Small volumes of anti-PBX1 antibody vial(s) may occasionally become entrapped in the seal of the product vial during shipment and storage. If necessary, briefly centrifuge the vial on a tabletop centrifuge to dislodge any liquid in the container`s cap. Certain products may require to ship with dry ice and additional dry ice fee may apply.

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.

PBX1_HUMAN

This gene encodes a nuclear protein that belongs to the PBX homeobox family of transcriptional factors. Studies in mice suggest that this gene may be involved in the regulation of osteogenesis, and required for skeletal patterning and programming. A chromosomal translocation, t(1;19) involving this gene and TCF3/E2A gene, is associated with pre-B-cell acute lymphoblastic leukemia. The resulting fusion protein, in which the DNA binding domain of E2A is replaced by the DNA binding domain of this protein, transforms cells by constitutively activating transcription of genes regulated by the PBX protein family. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq]

PBX1: 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. Forms a heterodimer with MEIS1 which binds DNA including a cAMP-responsive sequence in CYP17. Also forms heterotrimers with MEIS1 and a number of HOX proteins including HOXA9, HOXD4, HOXD9 and HOXD10. Interacts with PBXIP1. Expressed in all tissues except in cells of the B and T lineage. Belongs to the TALE/PBX homeobox family. 2 isoforms of the human protein are produced by alternative splicing.
