A human recombinant protein of amino acids 30-390 was used as the immunogen for the BANP antibody.
Btg3-associated nuclear protein controls V(D)J recombination during T-cell development by repressing T-cell receptor (TCR) beta enhancer function. Binds to scaffold/matrix attachment region beta (S/MARbeta), an ATC-rich DNA sequence located upstream of the TCR beta enhancer. Represses cyclin D1 transcription by recruiting HDAC1 to its promoter, thereby diminishing H3K9ac, H3S10ph and H4K8ac levels. Promotes TP53 Ser-15 phosphorylation and nuclear accumulation, which causes cell cycle arrest (By similarity).
