[[http://www.uniprot.org/uniprot/PBX1_HUMAN PBX1_HUMAN]] 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. TCF3-PBX1 transforms cells by constitutively activating transcription of genes regulated by PBX1 or by other members of the PBX protein family. [[http://www.uniprot.org/uniprot/HXB1_HUMAN HXB1_HUMAN]] Defects in HOXB1 are the cause of facial paresis, hereditary congenital, 3 (HCFP3) [MIM:[http://omim.org/entry/614744 614744]]. A form of facial paresis, a disease characterized by isolated dysfunction of the facial nerve (CN VII). HCFP3 patients are affected by bilateral facial palsy, facial muscle weakness of muscles innervated by CN VII, hearing loss, and strabismus.<ref>PMID:22770981</ref>

[[http://www.uniprot.org/uniprot/PBX1_HUMAN PBX1_HUMAN]] 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. Isoform PBX1b as part of a PDX1:PBX1b:MEIS2b complex in pancreatic acinar cells is involved in the transcriptional activation of the ELA1 enhancer; the complex binds to the enhancer B element and cooperates with the transcription factor 1 complex (PTF1) bound to the enhancer A element. Probably in complex with MEIS2, is involved in transcriptional regulation by KLF4.<ref>PMID:12609849</ref> <ref>PMID:21746878</ref> [[http://www.uniprot.org/uniprot/HXB1_HUMAN HXB1_HUMAN]] Sequence-specific transcription factor which is part of a developmental regulatory system that provides cells with specific positional identities on the anterior-posterior axis. Acts on the anterior body structures.
