| Function |
Sequence specific transcriptional activator which binds to the PU-box, a purine-rich DNA sequence (5'-GAGGAA-3') that can act as a lymphoid-specific enhancer. Promotes development of plasmacytoid dendritic cells (pDCs), also known as type 2 DC precursors (pre-DC2) or natural interferon (IFN)-producing cells. These cells have the capacity to produce large amounts of interferon and block viral replication. May be required for B-cell receptor (BCR) signaling, which is necessary for normal B-cell development and antigenic stimulation. {ECO:0000269|PubMed:10196196, ECO:0000269|PubMed:12393575, ECO:0000269|PubMed:1406622, ECO:0000269|PubMed:15583020}.

| Subcellular Location |
Isoform 1: Nucleus.
|
| Tissue Specificity |
Expressed in plasmacytoid dendritic cells (pDCs) and B-cells, not expressed in T-cells or granulocytes. May also be enriched in stem cell populations of the liver. {ECO:0000269|PubMed:11841448, ECO:0000269|PubMed:12393575}.
