The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Use a concentration of 0.5 - 1.5 µg/ml. Predicted molecular weight: 47 kDa.
FunctionBinds 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 specificityExpressed in all tissues except in cells of the B and T lineage.
Involvement in diseaseNote=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 similaritiesBelongs to the TALE/PBX homeobox family. Contains 1 homeobox DNA-binding domain.
