General annotation (Comments)
| 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. Required for B-cell receptor (BCR) signaling, which is necessary for normal B-cell development and antigenic stimulation. Ref.2 Ref.3 Ref.4 Ref.5 Ref.6 Ref.7 Ref.8 |
| Subunit structure | Can form homotypic interactions. Interacts with IRF4. May also interact with CREBBP, EP300, SPI1/PU.1 related, JUN and TBP By similarity. |
| Subcellular location | Nucleus Probable. |
| Tissue specificity | Expressed in the medulla of the thymus, the spleen and germinal centers of the lymph nodes. Expressed in B-cells and T-cells, expression increases during B-cell maturation and decreases during T-cell maturation. Ref.2 |
| Domain | The protein contains a weakly acidic N-terminal transactivation domain (TAD) followed by a second TAD rich in proline, serine and threonine. Each of these domains may be required for transcriptional activation of a subset of target genes By similarity. |
| Sequence similarities | Belongs to the ETS family. Contains 1 ETS DNA-binding domain. |

Alternative products
| This entry describes 3 isoforms produced by alternative promoter usage and alternative splicing. [Align] [Select] | ||||||
| Isoform IA (identifier: O35906-1) This isoform has been chosen as the 'canonical' sequence. All positional information in this entry refers to it. This is also the sequence that appears in the downloadable versions of the entry. | ||||||
| Note: Produced by alternative promoter usage. | ||||||
| Isoform IC (identifier: O35906-2) The sequence of this isoform differs from the canonical sequence as follows: 17-17: L → LVGEGVSPRPEMTLSSLRQ | ||||||
| Note: Produced by alternative splicing of isoform IA. No experimental confirmation available. | ||||||
| Isoform IIA (identifier: O35906-3) The sequence of this isoform differs from the canonical sequence as follows: 1-8: MLALEAAQ → MPLCLSPAR | ||||||
| Note: Produced by alternative promoter usage. |
