Product Detail	Pbx 1, 2, 3 and 4 are members of the TALE (three amino acid loop extension) family of homeodomain-containing proteins. Human pre-B cell acute leukemias are frequently associated with a t(1;19)(q23;p13.3) chromosomal rearrangement, which creates a chimeric gene encoding a fusion between the E2A and Pbx 1 gene products. Pbx 2 and Pbx 3 share 92% and 94% respective identities with Pbx 1 over a 266 amino acid region flanking their homeobox domains, while all three proteins are quite divergent at their amino- and carboxy-termini. Two forms of Pbx 1 and Pbx 3 each differ primarily in their carboxy-termini and result from alternative mRNA splicing. Unlike other homeotic selector genes which are expressed transiently during development and differentiation, Pbx gene transcripts are ubiquitously expressed in both fetal and adult tissues and cell lines. Additionally, Pbx 2 and Pbx 3 transcripts are detected in lymphoid cells, which do not express Pbx 1. Pbx 4 expression is confined to the testis, especially to spermatocytes in the pachytene stage of the first meiotic prophase. Function: PBX2 is a ubiquitously expressed member of the TALE/PBX homeobox family and was identified by its similarity to a homeobox gene involved in t(1;19) translocation in acute pre-B-cell leukemias. PBX2 is a transcriptional activator which binds to the TLX1 promoter, binding to the sequence 5'-ATCAATCAA-3'. It forms heterodimers with MEIS1, involved in activation of PF4 transcription, and heterotrimers with MEIS1 and HOXA9. The gene is located within the major histocompatibility complex (MHC) on chromosome 6. Subcellular Location: Nuclear. Tissue Specificity: Ubiquitously expressed. Post-translational modifications: Phosphorylated upon DNA damage, probably by ATM or ATR. Similarity: Belongs to the TALE/PBX homeobox family. Contains 1 homeobox DNA-binding domain.
