PBX1-2-3

Pre-B-cell leukemia transcription factor 1,2,3. Targeting all three. Transcription factor which binds the DNA sequence 5'-TGATTGAT-3' as part of a heterodimer with HOX proteins such as HOXA1, HOXA5, HOXB7 and HOXB8 (By similarity). Binds the DNA sequence 5'-TGATTGAC-3' in complex with a nuclear factor which is not a class I HOX protein (By similarity). Has also been shown to bind the DNA sequence 5'-ATCAATCAA-3' cooperatively with HOXA5, HOXB7, HOXB8, HOXC8 and HOXD4 (PubMed:7791786). Acts as a transcriptional activator of PF4 in complex with MEIS1 (By similarity). Also activates transcription of SOX3 in complex with MEIS1 by binding to the 5'-TGATTGAC-3' consensus sequence (PubMed:19799567). In natural killer cells, binds to the NFIL3 promoter and acts as a transcriptional activator of NFIL3, promoting natural killer cell development (PubMed:32190943). Plays a role in the cAMP-dependent regulation of CYP17A1 gene expression via its cAMP-regulatory sequence (CRS1) (PubMed:7913464). Probably in complex with MEIS2, is involved in transcriptional regulation by KLF4 (By similarity). Acts as a transcriptional activator of NKX2-5 and a transcriptional repressor of CDKN2B (PubMed:22560297). Together with NKX2-5, required for spleen development through a mechanism that involves CDKN2B repression (PubMed:22560297). (Source UniProtKB)
