General annotation (Comments)
| Function | Transcriptional coactivator for CREB1 which activates transcription through both consensus and variant cAMP response element (CRE) sites. Acts as a coactivator, in the SIK/TORC signaling pathway, being active when dephosphorylated and acts independently of CREB1 'Ser-133' phosphorylation. Enhances the interaction of CREB1 with TAF4. Regulates the expression of specific CREB-activated genes such as the steroidogenic gene, StAR. Potent coactivator of PPARGC1A and inducer of mitochondrial biogenesis in muscle cells. Also coactivator for TAX activation of the human T-cell leukemia virus type 1 (HTLV-1) long terminal repeats (LTR). Ref.1 Ref.7 Ref.8 Ref.11 Ref.13 Ref.14 Ref.15 |
| Subunit structure | Binding, as a tetramer, through its N-terminal region, with the bZIP domain of CREB1 enhances recruitment of TAF4 to the promoter. 'Arg-314' in the bZIP domain of CREB1 is essential for this interaction By similarity. Interaction with HTLV-1 TAX enhances its transcriptional activity. Interacts, via the N-terminal with the ankyrin repeats of BCL3, to form a complex with CREB1 on CRE and TxRE responsive elements and represses HTLV-1 LTR-mediated transcription. Ref.1 Ref.8 Ref.12 Ref.14 |
| Subcellular location | Nucleus. Cytoplasm. Note: Appears to be mainly nuclear. Ref.1 Ref.7 Ref.9 Ref.11 |
| Tissue specificity | Predominantly expressed in B and T lymphocytes. Highest levels in lung. Also expressed in brain, colon, heart, kidney, ovary, and prostate. Weak expression in liver, pancreas, muscle, small intestine, spleen and stomach. Ref.6 Ref.13 |
| Sequence similarities | Belongs to the TORC family. |
| Sequence caution | The sequence BAC03424.1 differs from that shown. Reason: Frameshift at position 82. |
